Dear useRs! I would like to generate a list of all possible (unique) partitions of N units into k classes. For example, all possible partitions of 4 units into 2 classes are (I hope I have not missed anyone): 1,1,1,2 (this can be read as {1,2,3},{4}) 1,1,2,1 1,2,1,1 2,1,1,1 1,1,2,2 1,2,1,2 1,2,2,1 The partitions 1,1,2,2 and 2,2,1,1 are the same and are therefore not two unique

A link in one of my help files does not work. I have in this help file: \seealso{\code{\link{crit.fun}}, \code{\link{opt.par}}, \code{\link{opt.random.par}}, \code{\link{opt.these.par}}, \code{\link{nkpartitions}}, \code{\link{nkpar}}, \code{\link{plot.check.these.par}} } Everything in one row, the last link does not work. In another help file, I have: \name{plot.mat} \alias{plot.mat} \alias{plot.crit.fun} \alias{plot.opt.par} \alias{plot.opt.par.mode} \alias{plot.opt.more.par} \alias{plot.opt.more....

Hi! Suppose I have m objects. I need to find out what are all possible ways I can group those m objects into r groups. Moreover, I need to create a matrix that contains what those arrangements are. I've created code for when r=2 but I've come to a halt when trying to generalize it into r groups. For example, if I have m=6 objects and I want to arrange them into groups of r=2, there
