Arguments

filename

(character(1))
Filename from which the configurations should be read. The contents should be readable by read.table( , header=TRUE).

parameters

(list())
Data structure containing the parameter space definition. The data structure has to similar to the one returned by the function readParameters.

debugLevel

(integer(1))
