sweep_cols.matrix

Suptract a elements of a vector from respective columns of a matrix

An optimized function equivalent to sweep(x, 2, STATS) for a matrix x.

sweep_cols.matrix(x, STATS, disable_checks = FALSE)

`x`	a numeric matrix;
`STATS`	a numeric vector whose length equals to the number of columns of `x`.
`disable_checks`	if `TRUE`, do not check that `x` is a numeric matrix and its number of columns matches the length of `STATS`; set in production code for a significant speed-up.

A matrix of the same attributes as x.

x <- matrix(runif(1000), ncol=4)
s <- 1:4

stopifnot(all.equal(sweep_cols.matrix(x, s), sweep(x, 2, s)))
