Yes, the 'm' is supposed to suggest "matrix" -- but actually I think
that's right.
We already have "smpl n --random" for datasets, and allowing a single
series argument to <function whose name is under discussion> would be a
little strange. You couldn't get a series back, it would have to be a
vector
OK, but now that we have established we don't need a blocksize for the
no-replacement case, why not go back to 'resample'?
1st arg: as before
2nd arg: 0 to indicate no replacement
3rd arg: (new and optional) sample size
Having the 2nd arg != 0 and the 3rd arg present would be an error. Of
course, using the 3rd arg might be considered sufficient and the 2nd arg
could be left empty (null) then.
