For the record, this is not a good answer to the question (and the
real answer is 'explained fully' on the help page for .libPaths, and
also in the rw-FAQ, Q4.2).
If you move your personal library directory, you need to set the
environment variable R_LIBS_USER .
And personal (not site) environment variables should be set in
~/.Renviron, not in Renviron.site. If you want a site library, that
is explained fully in the references in my first paragraph.

C:\myusername\Documents as C:\myusername\Documents\R\win-library

When I open and R and run the command library(BRugs) it works fine.
However, I would like to move the BRugs stuff out of my Documents
folder,
either to a subdirectory under Documents of my choosing or to
somewhere in
C:\Program Files\R\R-2.12.0. I tried just moving the whole folder and
subfolders R\win-library\2.12\... from Documents to a subfolder. I
don't
think this matters, but just to complete, there is also a folder
called Coda
with the BRugs folder in the 2.12 folder and of course there are
subfolders
and files under each of the folders Coda and BRugs. Then when I try
library(BRugs) I get the error message "Error in library(BRugs) :
there is
no package called 'BRugs'". So it seems R only knows to look for the
BRugs
package in it's original installation location.
How can I get it to work having BRugs in one of my desired locations?
Then you need to understand where R will be able to find your
packages, and how one might change that:
?libPaths

I'm posting a specific answer to my own question for the record since The
help for libPaths (actually should be ?.libPaths) doesn't explain this
fully. I created the file Renviron.site in the folder C:\Program
Files\R\R-2.12.0\etc and put the text R_LIBS =
C:/Users/myusername/Documents/.../R/win-library/2.12 in that file. The ...
represents the path for the subdirectory that I moved R\win-library\2.12\...
to.
