Hi, I plan to use R on IBM AIX machines (4.x.x), and hoping some feedbacks from R users on this OS. I've looked at the R search site, my impression is that there would be very few peoples who are currently using R on AIX, correct me if I'm wrong. To compile R on AIX, I have two little questions: 1. which compiles would be recommanded (IBM C & Fortran compilers vs GNU compiles), and are there any restrictions on the version to be used ? 2. is Perl 5.0.0 usable instead of the version 5.6.1 recommanded ? Many thanks in advance for your help -- Fan
