[Help-glpk] Processing glpsol output with R (was: Need help on interval planning constraint)

2009-12-28 Thread Robbie Morrison
Hello Jeffrey The quick answer is "not hard at all". RECOVERING JUST THE VALUES I suggest starting with the 'glpsol' option: --write filename : write solution in plain text format The first thing to determine is whether the problem is pure-LP or MIP. If not already known, this can be under

Hi Robbie and Jeffrey, R package, R Graphics and R Geo (maptools) are very GLPK / MathProg output friendly. In the days few days, I was able to use some of the difficult graphing problems I had. I even implemented joining tables (LP result) in shapefile and rendering the maps using R Geo (spatial

Want to try to run R in Gusek? Put this one in R.properties file #To compile model command.compile.subsystem.$(file.patterns.r)=0 command.compile.$(file.patterns.r)=$(r.winpath)Rscript --vanilla --slave "$(FilePath)" #To run model command.go.subsystem.$(file.patterns.r)=1 command.go.$
