Thank you Sharpie and Duncan. I am using Compaq Visual Fortran compiler on a Windows machine.
I tried with all small letters for the function names and created the DLLs. But somehow the DLL created only had all CAPS. But the DLL worked when I changed the function name to myxmean. Not really sure what changed but it worked fine :) Ravi -- View this message in context: http://r.789695.n4.nabble.com/Fortran-Symbol-Name-not-in-Load-Table-tp3508719p3513909.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
