## updates of installation bear with macOS (Mojave) [R for BE/BA]

Dear all,

This is to renew my previous post about installation of bear (or my other R packages using RGtk2 package. For Windows OS or Linux users, the previous posts still hold true. Now, the problem occurs with macOS (Mojave). If you upgrade R to current version (v3.6.1), you may need to read this carefully. The key point is the issue of RGtk2 package installation. As default from preinst.r, RGtk2 is installed as type="binary" which is default for install.packages() function. For most of R packages, this should be no problem at all with macOS. Unfortunately, RGtk2 is an exception. So we need to install RGtk2 correctly; otherwise you will get error messages something like    Error in dyn.load(file, DLLpath = DLLpath, ...) :   unable to load shared object '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/RGtk2/libs/RGtk2.so':   dlopen(/Library/Frameworks/R.framework/Versions/3.6/Resources/library/RGtk2/libs/RGtk2.so, 6): Library not loaded: /Library/Frameworks/GTK+.framework/Versions/2.24.X11/Resources/lib/libgtk-x11-2.0.0.dylib   Referenced from: /Library/Frameworks/R.framework/Versions/3.6/Resources/library/RGtk2/libs/RGtk2.so   Reason: image not found
And there will be a popup window to ask if ‘Need GTK+?’ which was a broken link and was unable to install GTK+ (driver). I have tried thousand times and failed to connect. However, if you can get it from it, do not use it. If you try to install RGtk2 from its source with install.packages("RGtk2",type="source"), you will get another error messages "... gtk is not found. gtk 2.8.0 or above is required.' That implies gtk+ installation previously using Homebrew is not recognized by R any more. So the following steps can resolve this problem (tested with bear v2.8.4/R v3.6.1 with macOS (Mojave)).
$sudo rm -rf /Library/Frameworks/R.framework 2. Install new R (R-x.x.x.pkg) and re-install gfortan_6.1.pkg (it is required; obtained it from CRAN mirror): Remember to install R first followed by gfortran_6.1.pkg. This is because gfortran will install some fortran/C/C++ header files into /R.framework; so we have to do it again; 3. Re-install RGtk2 and cairoDevice package as previous post; 4. Re-run source(“preinst.r”) under R console; 5. Re-install bear package. That's it.

The problem is when we try to retrieve a input data file with gfile() function from RGtk2, I usually get the error message as follows:(R:351): Gtk-WARNING **: 10:28:58.039: Attempting to read the recently used resources file at /Users/username/.local/share/recently-used.xbel', but the parser failed: Failed to open file “/Users/username/.local/share/recently-used.xbel”: Permission denied.  where username is your login name, of course. It does not matter at all because the package still can read the input file correctly. However, it just make me itch for a long time. Recently, I solve the puzzle. It can be easily fixed with a terminal and type  mkdir /Users/username/.local /Users/username/.local/share. Please do not use  sudo mkdir /Users/username/.local /Users/username/.local/share unless you run R with sudo R every time; otherwise you still get "... Permission denied". When I asked Google master several years ago, some nice people always suggested that we should use sudo mkdir /Users/username/.local /Users/username/.local/share to fix this problem. However, I still got ".... Permissions denied." That's because I did not use sudo R, instead of just R to run R. If you get this error messages, just fix it and do not let itch keeps bothering you. And this only occurs with macOS.

As default, it is installed using the binary (*.tgz) from CRAN. Then it will incur errors when using together with RGtk2 for macOS users. So please install or upgrade the package cairoDeivce from source, if running bear. Type install.packages("cairoDevice",type="source") in the terminal. It will fix the errors. Do the same thing for the package RGtk2 (install.packages("RGtk2",type="source")) upgrade later.

It is the same as previous steps on Mojave (see the attached picture). That is to install Xcode, Xcode commander line (both can be downloaded from Apple Development Center; login req.), MacPorts and XQuartz. Then install R v4.0.0 and GNU Fortran as described in CRAN website. No need to install RGtk2 & cairoDevice packages separately. I have already included these steps into 'preinst.r'. $ export PATH=/opt/local/bin:/opt/local/sbin:$PATH$ sudo port selfupdate $sudo port install pkgconfig$ sudo port install gtk2 +x11 

The only warning I had during running bear was:
Unable to create basic Accelerated OpenGL renderer. Unable to create basic Accelerated OpenGL renderer. Core Image is now using the software OpenGL renderer. This will be slow.

This is a new warning message to me. However, it still runs well. I need to find out how to solve the issue (OpenGL renderer stuffs; it seems there is no way to fix it. It's Catalina. OpenGL has been deprecated by Apple. Please see this and this).

So I would like to suggest that you may consider to remove R first from your iMac and try the setup steps again. If it still doesn't work, the you may consider to re-set your iMac back to factory default first (remember to back up all your important data/files before that!). Sorry to keep you waiting.

All the best,

## updates of installing bear/R v4.0.0 with macOS (Catalina)

Dear YJLee,
Thanks for your reply. I still have problems in running bear on R4.0.0, i get the following error message.

R v4.0.0 requires all packages rebuild for it. The binary file (*.tgz) on SourceForge now was built under previous version (R v3.6.x). So you need to download the source tarball file (*.tar.gz) of bear from here and place it in your working folder (getwd() to know where it is). Then open an terminal, type R CMD INSTALL bear_2.8.7.tar.gz [Enter]. It should work. I have done with upgrade to R v4.0.0 on Windows and macOS (both Mojave & Catalina). Now is waiting for linux-ubuntu (from its software update). Ps. (1) However packages binary built under R v4.0.0 can be installed for R v3.6.x without any compatibility issue. (2) R v4.0.0 seems running faster on Windows, but much slower on Catalina... just my gut feeling. » library(bear) » Error: package or namespace load failed for ‘bear’: » package ‘bear’ was installed before R 4.0.0: please re-install it All the best, -- Yung-jin Lee bear v2.8.9:- created by Hsin-ya Lee & Yung-jin Lee Kaohsiung, Taiwan http://pkpd.kmu.edu.tw/bear Download link (updated) -> here mahmoud-teaima ★ 2020-04-29 21:00 (352 d 08:03 ago) @ yjlee168 Posting: # 21368 Views: 14,184 ## tricks of R v4.0.0 Dear YJLee, Thanks for the detailed guidance.

Indeed. It’s a workstation. All Xeons (for servers and workstations) have their desktop counterparts with the same architecture. For my Xeon it’s a Core i3. The main differences are: Generally larger L3-cache, require motherboards with other chip­sets than desktop systems supporting server-grade unbuffered ECC RAM, rated for continuous 100% CPU load. Since I regularly run simulations 24/7 (for weeks) and a [email protected]-client, the last two points are important for me. All this stuff is more expensive: Such mainboards are produced in much lower numbers, the EEC RAM is more complex, and last but not least the CPU itself. Previously I had Dell workstations with double Xeons (i.e., before multi-cores were available) but the howling fans drove me crazy.

It sounds like gtk+ driver was not installed correctly. Did you install gtk+ driver with Macport first? $ export PATH=/opt/local/bin:/opt/local/sbin:$PATH$ sudo port selfupdate $sudo port install pkgconfig$ sudo port install gtk2 +x11

Make sure all above four steps end up with no error. Then run source("preinst.r") again. If you still get some errors, you may consider removing all R first. And re-install R (I saw you installing R v3.6.x from your messages.)

Thanks YJ. I re-installed R, now 4.0.0, and the 4 steps below work with no error. Then after running preinst.r and re-installing bear, I get the following error

## still having problems w/ bear v2.8.8 for R v4.0.0 for macOS

Hi Jay,

It's still the problem of gtk+ driver. Could you do install.packages("RGtk2", type="source") to see if you can install RGtk2 package from its source? This can verify if you have gtk+ driver installed correctly as we have discussed before.

Hi Jay,

Please download preinst.r from here and place it in your working directory, together with bear_2.8.8.tgz. Then run source("preinst.r"), and do("bear","bear_2.8.8.tgz"). This will re-install all required R packages with 'depend=TRUE' option, as well as bear. Good luck.

Ps. I don't know when the default of dependencies (or depend in short) option in install.packages() has been changed to 'NA'. It's default used to be 'depend=TRUE'.

Yung-jin,

» I don't know when the default of dependencies (or depend in short) option in install.packages() has been changed to 'NA'. It's default used to be 'depend=TRUE'.

Never (see the NEWS).
The default was/is install.packages(..., dependencies = NA). The man-page states:

The default, NA, means c("Depends", "Imports", "LinkingTo").

## depend = NA means ...

Dear Helmut,

Right and thank you very much for your info. But this depend option within install.packages(...) has two choices, one is 'NA' and the other is 'TRUE'. And you're correct, when it is 'NA'(default), means c("Depends", "Imports", "LinkingTo"). Does here 'NA' mean or imply 'FALSE' or what? If yes, why not using 'FALSE' instead of 'NA'? So I guess 'NA' is not 'FALSE' for depend option. NA is... NA.

## install.package() for the source packages

Dear Yung-jin,

let me comment
» Right and thank you very much for your info. But this depend option within install.packages(...) has two choices, one is 'NA' and the other is 'TRUE'. And you're correct, when it is 'NA'(default), means c("Depends", "Imports", "LinkingTo"). Does here 'NA' mean or imply 'FALSE' or what? If yes, why not using 'FALSE' instead of 'NA'? So I guess 'NA' is not 'FALSE' for depend option. NA is... NA.

From the man:
The default, NA, means c("Depends", "Imports", "LinkingTo"). TRUE means to use c("Depends", "Imports", "LinkingTo", "Suggests") for pkgs and c("Depends", "Imports", "LinkingTo") for added dependencies
So 'TRUE' is closer to NA. That's really a bit confusing and I don't know the history of that function argument. If set to 'FALSE', R still stop and warn you so you can decide what you would like to do
By the way if you install locally that's another story, since
Not used if repos = NULL...
So it is not possible to install dependent packages for a locally installed package within install.package()
There are solutions available:
- use devtools::install_local; there's an option to install dependencies from CRAN
- create and use your own repo

Kind regards,
Mittyri

Dear mittyri,

» ... By the way if you install locally that's another story, since
» Not used if repos = NULL...
» So it is not possible to install dependent packages for a locally installed package within install.package()

Exactly. Recently I just wondered: I used to do install.packages("foo") for all dependent or required packages before installing bear. That meant I used install.packages("foo",depend=NA) as default. And it was OK. Now I use install.packages("foo",depend=TRUE) and it is OK too. So I was wondering if we really need to set depend=TRUE. I also found if I set depend=TRUE R will install much more packages in that case. For example, I need to install package A. Package A depends on 3 packages (package B, C and D). Should I also install simultaneously package B, C and D? Furthermore, if package B depends on another 3 packages (package E, F & G), then will the option of depend=TRUE for package A also enable R to install package E, F & G? Therefore, I do not think we need to set depend=TRUE. I think R will check all required packages first for the package that we want to install. Then R will install these required packages first and leave the package that we need to install at last. Am I correct?

» There are solutions available:
» - use devtools::install_local; there's an option to install dependencies from CRAN

Great. I will try that.

» - create and use your own repo

Unless go to Github. Not a chance for Sourceforge. I will think about that too.

## desription Suggests section

Dear Yung-jin,

That meant I used install.packages("foo",depend=NA) as default. And it was OK. Now I use install.packages("foo",depend=TRUE) and it is OK too. So I was wondering if we really need to set depend=TRUE.

Then R will install these required packages first and leave the package that we need to install at last. Am I correct?

the difference between NA and TRUE is that the latter installs the packages from 'Suggests' section. They are not necessary for the essential package functions work (in theory).
You don't need to resolve the tree of dependencies of the packages, R will do that for you and installs all the tree (dependencies=TRUE just installs a little bit more). So just add an 'A' package inside imports section of description.
And yes, you don't need dependenices=TRUE, keep it with default value.

Kind regards,
Mittyri

Hi, I am new to R and to this Forum, so I am not sure if this is the correct space to "Reply" or not. However, I keep getting the same error message that Jay got above even after I deleted both R and bear from my computer (Windows) and the Re-installed R 4.0.0 and bear successfully in that order. I did that twice and still got the same error message.

## errors of installation bear (R v4.0.0) on Windows

Hi Andrew,

Please find bear_2.8.8.zip (built under R v4.0.0) in my Google cloud HD and download it. In addition, you should download preinst.r from SourceForge. Place the zip file and preinst.r under your R working directory. Open R console (Rgui.exe) as the system administrator, and type source("preinst.r") first, and then do("bear","bear_2.8.8.zip"). It will install all required R packages, as well as bear for you. When it finishes, close R console now and re-open it as the system admin again. Type library(bear) and go(). Now the system shows a pop-up dialogue and ask if you want to install GTK+ driver. Click install GTK+ driver. When it finishes, bear GUI will show up on your screen. Close it and also close R console. Now you can open R console as a general user. This is pre-release for bear v2.8.8. I still work on Hotelling's T2 of outlier detection analysis (ODA) (hopefully you do not need this test right now.). Other functions in this pre-release work fine. That's it.

Thank you for posting your question here. Let me know if you still have any problem to install bear on Windows.

Unfortunately my screen says the following:

Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘.gwindow’ for signature ‘"guiWidgetsToolkitRGtk2"’

Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called ‘gWidgetsRGtk2’

It is not the first time I install Bear for academic purpose, so...I installed gWidgetsRGtk2 and try again to install GTK, but nothing happens...my screen stops to talk to me...
Please, let me know what else I have to do.

Dear Yung-jin Lee
After I realized gWidgets and gWidgetsRGtk2 were not available as usual in CRAN, I just download both files.
I decide to remove BEAR package then...

I tried to load RGtk2, apparently something was wrong with the package:

Failed to load RGtk2 dynamic library, attempting to install it. Please install GTK+ from http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.1-20101227_win32.zip If the package still does not load, please ensure that GTK+ is installed and that it is on your PATH environment variable IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN Error: package or namespace load failed for 'RGtk2':  .onLoad failed in loadNamespace() for 'RGtk2', details:   call: NULL   error: stack central desbordado

I reinstalled RGtk2 from CRAN repositories. Because cairoDevice is related whit GUI functionality, I decided reinstall it also, then:
library(RGtk2)
Dialog box opened then I agreed with installation of GUI. Later I installed gWidgets, when it finished I installed gWidgetsRGtk2, both from local files:
utils:::menuInstallLocal() package ‘gWidgets2’ successfully unpacked and MD5 sums checked utils:::menuInstallLocal() * installing *source* package 'gWidgetsRGtk2' ... ** package 'gWidgetsRGtk2' successfully unpacked and MD5 sums checked ** using staged installation ** R ** inst ** byte-compile and prepare package for lazy loading ** help *** installing help indices   converting help for package 'gWidgetsRGtk2'     finding HTML links ... done     as.gWidgetsRGtk2                        html      gWidgetsRGtk2-misc                      html      gWidgetsRGtk2-package                   html      gWidgetsRGtk2-undocumented              html      gdfedit                                 html  ** building package indices ** testing if installed package can be loaded from temporary location ** testing if installed package can be loaded from final location ** testing if installed package keeps a record of temporary installation path * DONE (gWidgetsRGtk2)
Finally I installed BEAR v 2.8.8.
utils:::menuInstallLocal() package ‘bear’ successfully unpacked and MD5 sums checked`

It Works perfectly now...

Sorry for my late response, I had to verify my notes.

OK.

» [...] Later I installed gWidgets, when it finished I installed gWidgetsRGtk2, both from local files:

However, what you installed was gWidgets2, not gWidgets.

So bear can work with gWidgets2 too? I doubt it. I guess that you must install/upgrade R into the same file directory. That can keep gWidgets package unchanged. Accidentally perfect?

That's fine. Thanks for your response.

Oops! the downloaded file was gWidgets_0.0-54.tar.gz, so the installed file was gWidgets. No perfection in this typo mistake.
