There are a million ways to do this, probably.
brks <- c(1,sort(sample(seq_len(99),3)),100) ## 4 random groups
and then use brks as the breaks parameter in cut() with include.lowest = TRUE
?cut

I want to partition this into 4 random groups wheren n1 + n2 + n3 +
n4 = n
and ni is the number of elements in group i.
Try assigning with a sample() from:
unlist(mapply(rep, c(1:4), each=c(n1,n2,n3,n4)))
