Dear R People: Hao Yu has a very nice package for mpi in R. I'm trying to experiment on my own and am looking at building a shared library with objects from mpicc. I tried to compile a .o object and then use R CMD SHLIB to compile the shared library. But I'm getting errors with the MPI_Init function, which is the first MPI function in the subroutine. Any suggestions please? (or maybe i should just leave well enough alone) thanks, Erin Hodgess mailto: hodgess at gator.uhd.edu
