[R] Interfacing between Optimization Software and R
Dear all I was wondering, if there are reasons for R-Users to use (commercial) solver packages like GAMS, AMPL, Matlab, etc. These packages can solve all kind of mathematical optimization problems like (non-) linear problems, mixed complementarity problems, etc. Why I want to know? GAMS corporation developed a R package to send data from GAMS to R (or vice versa). It is called gdxrxw. I use this package a lot for my network models I solve with GAMS, sending the results from GAMS to R for plotting, generating tables in LaTeX and statistical analysis (see some of my post on blog.modelworks.ch). However, until now, for my personal use, I don't use the package the other way around (R -> Gams). I am writing a small article on this interface and was wondering if there are situations, where R-Users would be grateful for having the possibility to interact with solver software. Any reaction would be very much appreciated. Renger ____________________ Modelworks Gewerbestrasse 15 3600 Thun - Switzerland +41 79 818 53 73 Info at modelworks.ch blog.modelworks.ch

You missed a lot of indications, most prominently the task view http://cran.r-project.org/web/views/Optimization.html On 11/03/2012 07:18, Renger van Nieuwkoop wrote:> Dear all > > I was wondering, if there are reasons for R-Users to use (commercial) solver packages like GAMS, AMPL, Matlab, etc. > These packages can solve all kind of mathematical optimization problems like (non-) linear problems, mixed complementarity problems, etc. > > Why I want to know?
