Hi
I am sure I am missing something really basic, but I can't figure it out.
I want to start R so that I can specify the location for the Library tree. In
principel simple:
As I only want it dependent on the directory I stat R in, I put a .Rprofile
file in the directory.
My default path is:
> .libPaths()
[1] "/home/rkrug/R/i686-pc-linux-gnu-library/2.15"
[2] "/usr/lib/R/site-library"
[3] "/usr/lib/R/library"
>
But I want to have it
> .libPaths()
[1] "/home/rkrug/THE_DIRECTORY/library"
[2] "/usr/lib/R/library"
>
The first part is easy:
.libPaths("/home/rkrug/THE_DIRECTORY/library")
but how can I remove the site library?
If I set
In R 15.2 under Ubuntu, started with
R --vanilla
> .libPaths()
[1] "/home/rkrug/R/i686-pc-linux-gnu-library/2.15"
[2] "/usr/lib/R/site-library"
[3] "/usr/lib/R/library"
> .Library.site
[1] "/usr/lib/R/site-library" "/usr/lib/R/library"
> .Library
[1] "/usr/lib/R/library"
> .Library.site <- "" .Library.site
[1] ""
> .libPaths()
[1] "/home/rkrug/R/i686-pc-linux-gnu-library/2.15"
[2] "/usr/lib/R/site-library"
[3] "/usr/lib/R/library"
> .libPaths("") .libPaths()
[1] "/usr/lib/R/site-library" "/usr/lib/R/library"
> .Library
[1] "/usr/lib/R/library"
> .Library.site
[1] ""
>
> .libPaths("") .libPaths()
[1] "/usr/lib/R/site-library" "/usr/lib/R/library"
>
even executing
> .libPaths(.libPaths())
does not change anything.
Am I missing something or is there a bug in .libPaths()?
Cheers,
Rainer
