Hello,
Thanks, part of the problem was solved when I corrected the typo. Now it
recognizes one of the missing directories.
> .libPaths()
[1] "C:/Program Files/R/win-library/2.15" "C:/Program
Files/R/R-2.15.1/library"
That typo is in the original files, I haven't changed that part, just
tested if R, Rgui and Rterm were reading Rprofile.site by changing the
options("help_type") setting from "html" to "text" and back to "html".
It all went well.
And yes, the directories C:/Program Files/R/win-library and C:/Program
Files/R/win-library/2.15 do exist. So now I'll play with the
Rprofile.site file a bit to see if the other directory can also be found
at startup or by .libPaths(new).
Just played a bit. With .libPaths(new = a dir I want). It doesn't extend
the path, it overrides the previous setting. So, since in Rprofile.site
C:/Program Files/R/win-library comes before C:/Program
Files/R/win-library/2.15, only the latter is in effect during the R
session. This is documented behaviour, " If called with argument |new|,
the library search path is set to the existing directories in
|unique(c(new, .Library.site, .Library))| and this is returned." So I've
tried with a vector with two elements,
new <- c("C:/Program Files/R/win-library", "C:/Program
Files/R/win-library/2.15")
.libPaths(new = new)
.libPaths()
[1] "C:/Program Files/R/win-library" "C:/Program
Files/R/win-library/2.15"
[3] "C:/Program Files/R/R-2.15.1/library"
All well now, I just have to edit Rprofile.site.
Thanks a lot, your tip solved the problem.
