I installed R on my Windows laptop in C:\Program Files\R\R-2.15.2
and am able to open RGUI (640bit), see packages and run commands. However,
when I test the installation and run the basic tests and all the tests on
the standard and recommended packages i.e.:
library("tools")
testInstalledBasic("both")
testInstalledPackages("base", errorsAreFatal = FALSE)
testInstalledPackages("recommended", errorsAreFatal = FALSE)
I am getting errors such as:
> testInstalledPackages("base",errorsAreFatal=FALSE)
Error in setwd(outDir) : cannot change working directory
my working driectory is:
>getwd()
[1] "C:/Users/jpapa/Documents"
In which I see R folder as well as the .rData from my last session.
what does the wd have to do with the output directory? Do I need to create
an output directory? DO I need to setwd(outDir)?
do i need to change the wd (for example to the Pogram Files directory where
R is installed or to another directory I need to create? if so, how do I do
this?
i also noticed that i have packages in
\library C:/Users/jpapa/Documents/R/win-library/2.15
and in library C:/Program Files/R/R-2.15.2/library.
Do all packages need to be in one place? If so, should they be in my
Documents or in Program Files?
Thank you for your help.
