[R] R and marine protected areas: algorithms for site selection

[Rich Grenyer]

Hi - I looked briefly a little while ago for R interaction with linear 
programming tools. There is limited support for the lp_solve solver 
(http://sourceforge.net/projects/lpsolve) in the package lpSolve, but 
it doesn't give full access to the external solver's capabilities. 
Other than that, you may want to look at the Gnu Linear Programming Kit 
(http://www.gnu.org/software/glpk/glpk.html) and MathProg or Zimpl 
(http://www.zib.de/koch/zimpl/), and be prepared to get R to write text 
files that can then be run externally. Ugly, but you may get somewhere.

If you find anything better that integrates R and linear programming, 
I'd be interested to hear about it.

Regards,

Rich
