The function generates random partitions. The function is meant to be called by the function optRandomParC.
genRandomPar(k, n, seed = NULL, mingr = 1, maxgr = Inf,
addParam = list(genPajekPar = TRUE, probGenMech = NULL))Number of clusters (by modes).
Number of units (by modes).
Seed for generating random numbers (partitions).
Minimal allowed group size.
Maximal allowed group size.
This has to be a list with the following parameters (any or all can be missing, then the default values (see usage) are used):
"genPajekPar" - Should the partitions be generated as in Pajek (Batagelj & Mrvar, 2006). If FALSE, all partitions are selected completely at random while making sure that the partitions have the required number of clusters.
probGenMech - Here the probabilities for 4 different generating mechanisms can be specified. If this is not specified, the value is set to c(1/3, 1/3, 1/3, 0) if genPajekPar is TRUE and to c(0, 0, 0, 1) if genPajekPar is FALSE. The first 3 mechanisms are the same as implemented in Pajek (the second one has almost all units in only one cluster) and the fourth is completely random (from uniform distribution).
A random partition in the format required by optRandomParC. If a network has several modes, then a list of partitions, one for each mode.
