[R] Calling Other (non-C or Fortran) Programs from R

[Tim F Liao]

Thanks to both Duncan Murdoch and Brian Ripley.  LEM indeed 
is the program that Brian referred to in his response, a 
program for latent class/trait loglinear and event history 
analysis compiled with Borland Pascal.  There's a dos 
version and a windows version.  Not sure the program will 
produce dll's, but I'll do a bit exploration and report back.
