Sorry, I forgot to be more specific. I am using Windows XP.
I am using R.12.2 I installed both packages from the install packages menu. I always write library(name.of.library), and it is enough. But when I write library(nlme), R does not find nlme right away I load nlme first and it says package was downloaded succesfully. However, when I try to do this again in another day, R cannot find nlme, so I try to load mgcv with library(mgcv), then I get this message: Error: package 'nlme' could not be loaded In addition: Warning message: In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc) : there is no package called 'nlme' Is there any problem with nlme that I need to install it every time I open R?
