Hi everybody,
How can I transform a 0/1 matrix into a TRUE/FALSE matrix, and vice versa?
If A is your matrix, and you really want 0 to be TRUE (a little
weird...), just use
A == 0
and you get a logical matrix. To go the other way, as.numeric will
convert TRUE to 1 and FALSE to 0; if you don't want that, pre- or
post-process.
