Any chance some improvements can be made on table()?
table() is probably one of the most used R functions when working
interactively. Unfortunately it can be incredibly slow, especially
on a logical vector where a simple sum() is hundred times faster
(I actually got into the habit of using sum()
Hi,
table1D() below can be up to 60x faster than base::table() for the 1D
case. Here are the detailed speedups compared to base::table().
o With a logical vector of length 5M: 11x faster
(or more if 'useNA="always"')
o With factor/integer/numeric/char
