Hi : Whenever I try to run R in a second session( but not in the same working directory ) , I get the error below Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/u/etlfs/dev/users/leedsmar/res/R/lib/chron/libs/chron.so': /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /u/etlfs/dev/users/leedsmar/res/R/lib/chron/libs/chron.so) I kind of understand the error but, given that my R path is what it is below /ms/dist/fsf/PROJ/R/2.3.1/lib/R/bin does anyone know where /lib/i686/libc.so should be ? in other words is the lib before the i686 the same lib as the one before the R/bin ? I'm just trying to figure this out and if anyone could point out any relevant doc, that would be great. My R works fine. This only happens when I try to run two sessions. -------------------------------------------------------- This is not an offer (or solicitation of an offer) to buy/sell the securities/instruments mentioned or an official confirmation.
