install.package() for the source packages [R for BE/BA]

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
