v1.2.9 >>>> April 2, 2012
#  (1) fixed a bug pointed by Dr. Anton Korobeynikov 
# <anton@korobeynikov.info>
# Dear Dr. Weiliang Qiu,
# 
# Recently we tried to used your package clusterGeneration but found
# that the behavior of genRandomClust() with clustszind == 3 is
# definitely wrong compared to the one documented.
# After looking into the implementation it became obvious that
# genMemSize() function does wrong things: it tries to sample from 1:G
# using provided clusterSizes as weights. Surely the output clusters
# have wrong sizes (not the ones specified).
# 
# The fix is pretty simple: change the code for clustszind == 3 to
# something like this:
# 
# mem <- sample(unlist(lapply(1:G, function(x) rep.int(x, times =
# clustSizes[x]))))
# N <- sum(clustSizes)
# 
# Or, maybe if you want to keep the current behavior it'd be better to
# introduce new clustszind variant.
# #
#
#  (2) add 'clustSizes<-as.integer(clustSizes)' before checking
#      '!is.integer(clustSizes[i])'
#

# argument match of 'sym' to 'symmetric'
