The call is invalid:
Sweep out Array Summaries
sweep(x, MARGIN, STATS, FUN="-", ...)
x: an array.
If you call sweep on a data frame, as in
> sweep(crimes, 2, "-")
it does not work: it should not have done so before. On the other hand, in
0.62.2, valid arithmetic operations on data frames gave matrices,
which helped your illegal example but were incorrect on legal ones.
You need an as.matrix in your code, I believe.
This example also fails in S.
