[R] Integer programming in R

[apjaworski@mmm.com]

Robin,

This is not a direct answer to your question, but there exists a pretty
good linear, mixted and integer programming package called lp_solve.  I
have used it successfully  on a couple of projects.  As far as I know it is
in the public domain and there is source code available.  There is also a
precompiled version available for Windows Visual Basic environment
containing a precompiled DLL and an interface module defining VB function
calls to the DLL.  I think, that having all that it should be possible to
get something going in R, at least in the Windows environment.

Hope this helps,

Andy

Dear all,

I am a relative newcomer to the R language, and am sussing out
the possibilities of using R to do integer programming (which I am
also new to).  Is there something along the lines of the NUOPT S-
PLUS package that is available, or on the way, for R?  Are there
other options for integer programming in R?

Thanks very much in advance,
