Unable to install ggplot2

Question

I'm having trouble installing ggplot2 into R. I've looked around here and haven't seen the same error that I'm getting.

> install.packages('ggplot2', dep=TRUE)
Warning in install.packages("ggplot2", dep = TRUE) :
  'lib = "C:/Program Files/R/R-2.13.1/library"' is not writable
Error in install.packages("ggplot2", dep = TRUE) : 
  unable to install packages

Can anybody help?

Solution 1

It would actually suffice to invoke as follows:

> install.packages('ggplot2', dep=TRUE, lib=NULL)

and R should substitue lib with the default location, as in my comment.

Or you could change the environment variable itself.

Solution 2

R needs to have write access to your library to install a package there. The other advice you're getting is good and should be preferred, but you can run R (or RStudio) as an administrator (right-click on the .exe and "Run as Administrator" is an option) which should give it write access to your library.

Thanks for the reponse, I tried your suggestion and got the same error. How do I change the environment variable? I just installed R on the computer I'm using, could I have done something wrong when I installed R on my computer?

Than you should create the directory for R libs, for example using the path I use, and supply it's path as a value for the lib argument. And after that, follow Dirk's advice :)
