Have you looked at the R interface to GLPK (the GNU Linear Programming Kit)?

No. Note that SIMPLE is the language of NUOPT, not of S-PLUS. There is
an (extra-cost) interface module S+NUOPT, but it is an interface to
NUOPT's engine.
As far as I am aware R itself covers almost none of the ground of S+NUOPT,
and available packages cover only a small part of it.
