That's a good idea -- always using the same folder name for R.

Do you mean your R_LIBS has two components: one to look in
..\R\rcurrent\library and a second to look in ..\R\library? What does
it look like exactly?
When you do install.packages(whatever) does it install to the
..\R\library rather than ..\R\rcurrent\library ? Also, does
updates.packages() work as expected for you?

I think its necessary to rebuild the name data base in miktex too
initexmf -u
although ignoring that step may work as long as the filenames
have not changed. I was hoping to continue using a vanilla
miktex installation as I do now rather than having a custom miktex.ini
file. At any rate my batch file would continue to work even with your setup
so I think I should be ok here.

It occurs to me in reading this that I could keep the *.site files in
..\R and then have my miktex update batch file also copy them
to the appropriate etc folder. Thus keeping an R\library folder
and running the batch file after each new installation would
address 1, 2 and 4 even without using the same name for the
rw... folder. This still does not handle the shortcut key which
I would have to handle manually or determine if there is a way
I could also add that to my batch file.
