[R] Windows 7 issues with installing packages and setting library paths

[Christoph Scherber]

Dear all,

I am forced to work in an environment without administrator rights.

When using R2.13.1 on Windows 7 (64-Bit), I found that I can´t install or update any packages due to missing writing permissions.

I managed to get full access to a directory on my C:\ drive now - but how do I specify that all libraries shall be installed into this directory?

In Rcmd_environ I have the following entries:
## from R.sh
R_SHARE_DIR="C:\\Program Files\\R\\R-2.13.1\share"
R_INCLUDE_DIR="C:\\Program Files\\R\\R-2.13.1\share\include"
R_DOC_DIR="C:\\Program Files\\R\\R-2.13.1\share\doc"
R_ARCH=
R_LIBS_USER="C:\\Program Files\\R\\R-2.13.1\\library"
R_LIBS="C:\\Program Files\\R\\R-2.13.1\\library"


In Rprofile.site I have the following entries:

.Library.site="C:\\Program Files\\R\\R-2.13.1\\library"
.Library="C:\\Program Files\\R\\R-2.13.1\\library"
.libPaths="C:\\Program Files\\R\\R-2.13.1\\library"

What else do I need to change?

When I start up R, I get the following error message:

Error: cannot change value of locked binding for '.Library'

When calling .libPaths, I still get the wrong path:
"\\\\winfs-uni.top.gwdg.de/cscherb1$/R/R-2.13.1/library"


R has been installed at
"C:\\Program Files\\R"

but for some reason it still uses
"winfs-uni.top.gwdg.de/cscherb1$/R"

as the default directory for libraries (where I don´t have write permissions for some unknown reasons)

What can I do to change the default library installation location?

Any help would be greatly appreciated!

Many thanks and best wishes
Christoph
