Hi BE-proff,

❝ […] R-console doesn't want to see TOST library :angry:

Define “doesn’t want”. ;-)

❝ Maybe R doesn't work with Windows 8?

Oh, it does. AFAIK, Detlew developed the latest version under Win8.

Try this:

Type (.packages())
If PowerTOST is not in the list, you either have not loaded it or it is not available at all.
Type library()
A new window opens showing all installed packages. If PowerTOST is not in the list you need to download/install it first (see here).
If it is in the list, type library(PowerTOST)
If you get an error, post the text here. Screenshots are sometimes difficult to read – or does R crash?
If loading works, check this: sampleN.TOST(CV=0.3)
Should give at the end n=40 and power=0.815845.

❝ BTW is there a "support" where I could place a screenshot with the error? ;-)

Nope, there is no “support” in R. Generally you could ask the maintainer(s) of packages. You find the contact e-mail(s) in the DESCRIPTION-file. Type packageDescription("foo"), where foo is he name of the library.

PS: Sometimes we forget to post the required libraries here. Without library(PowerTOST) in the current R-session – if you copy/paste sampleN.TOST(CV=0.3) – R will tell you:
Error: could not find function "sampleN.TOST"
In my posts (containing multiple code sections) I start with library(foo) on top. Of course, if someone tries only a later part, an error will be thrown. I will change my habits and start all sections with library(foo).

PPS: For the code posted above you don’t need to load anything.
