R Experts,
I had a problem when trying to install package tm. The install looked
successful ("Package 'tm' successfully unpacked and MD5 sums checked") but I
could not load it through
library(tm). It kept complaining that tm package was not installed.
So it was through this problem that I realized I had two locations where my
packages are stored:
C:R/R-3.0.2/library #Preferred
\\\\lab.gov/users/lopez/Data/documents/R/win-library/3.0 #NOT Preferred
I am not sure when and how the second location was created. But now I want to
change my default location to the "Preferred" location.
I referred to
http://stat.ethz.ch/R-manual/R-devel/library/base/html/libPaths.html but I
don't understand how to set the environment variables R_LIBS or R_LIBS_SITE,
which is what I understood I need to do. I looked in R\R-3.0.2\etc and did not
find a Renviron file (per
http://mathematicalcoffee.blogspot.com/2013/04/getting-rstudio-to-include-your.html).
So I created one (file name exactly as "Renviron") and set the variable
(R_LIBS_USER=~/R/library) there but when I do the following I still see both
library paths:
> .libPaths()
[1] "\\\\lab.gov/users/lopez/Data/documents/R/win-library/3.0"
"C:/R/R-3.0.2/library"
I only want the preferred path. How do I remove the unwanted path?
BTW I did find a solution to installing tm properly but want to prevent similar
problem from happening in the future by only having one library path.
