Several of us locally are puzzling over the following problem:
We have a central repository of R packages on our linux system.
Occasionally, we'd like to install a different version of the same
package (such as making updates to the survival package before it is
released to the larger group, or a downloaded beta version). When
using the library function, it appears that lib.loc is not being used
and instead the central repository is being used. We've even tried
modifying .libPaths( ) so that our local path is first in the search
list. Is this a bug or a "feature"?
For example:
>
install.packages('DBI',lib='/data1/bsi/epi/s105816.SNPlinkage/CNV/rlib')
> library(DBI,
lib.loc='/data1/bsi/epi/s105816.SNPlinkage/CNV/rlib')
I can look in my directory and see that DBI is version 0.2-5,
but when I use the library command I get the version installed in the
central location instead of in my specified directory.
> library(help=DBI)
