If all rows are in the same "group", rowsum() returns a vector instead of a
(1xN) matrix, contrary to documentation:
R> print(z <- rowsum(matrix(1:12, 3,4), rep("x",3)))
[1] 6 15 24 33
R> dim(z)
NULL
It worked correctly in version 1.4.0 but was broken by version 1.6.1. I'm
currently using 1.7.1 under Solaris 2.8.
