Hello,
I am performing Latin Hypercube sampling from functions "makeParamSet" and
"generateDesign" (package "ParamHelpers") in R. Using the function
"makeParamSet", how can I specify a formula to define a given parameter ? Here
is an example where "g� is the product of �a� and �c�:
ps <- makeParamSet(makeIntegerParam("a", lower=800, upper=7200),
makeIntegerParam("c", lower=632, upper=5688),
makeIntegerParam("e", lower=5, upper=45),
makeIntegerParam("b", lower=0, upper=7200),
makeIntegerParam("d", lower=0, upper=5688),
makeIntegerParam("f", lower=0, upper=45),
makeIntegerParam("g", trafo = function(a,c) a*c),
forbidden = quote(d > g))
Y <- generateDesign(100, ps, trafo = T)
Problem:
With the code, I have the following error:
Error in doBasicGenDesignChecks(par.set) :
Finite box constraints required!
Thank you very much for your help.
Nelly
