And while I'm at it: I also noticed trimr() which trims rows.
Don't know
whether that's new, but why introduce a special function for this
operation, couldn't it always be easily done by indexing, as in
M[ttop+1:rows(M)-tbot] ?
It could. But one point to bear in mind (apart from
user-friendliness) is that a built-in shortcut such a trimr()
is in principle more efficient than the long-hand version, since it
involves less parsing of user input. Whether that's of practical
importance, I'm not sure.
