[R] default library locations under Linux

[Tony Long]

All:

I am attempting to allow multiple users on a linux system use some 
common functions.  The problem I am having is that for some users 
their default library location is

.lib.loc = "/usr/lib/R/library"

whereas for other users it is

.lib.loc = "/usr/local/lib/R/library"

It seems as though the packages (for example cluster) load fine if I 
just change .lib.loc to "usr/lib/R/library"  but when I go to run the 
functions I get additional errors like:

Error in .fortran("pam",as.integer(n), ...:  C/Fortran function name 
not in load table

I suspect I don't have a clue how to global "synchronize" my linux 
installation of R so that all users see the same packages (clearly 
just changing .lib.loc doesn't do the trick), and I have to do it at 
a "higher" level than the .lib.loc.

I think it is likely the whole problem stems from how I installed 
these packages.  Namely being in my personal account as su, starting 
R, and using the install.packages() {this function is cool to the 
point of being dangerous}.  Maybe I should be running the 
install.packages option from another directory.  Any advice here 
would also be appreciated.

Any suggestions.  Tony
