Column Sums — colSummations • sigscores

This function computes the sum for each column in an input matrix.

Usage

colSummations(x, rows = NULL, na.rm = TRUE, ...)

x: a numerical matrix features-by-samples
rows: (optional) numerical vector giving the rows in x or character vector matching the row names in x to operate over. If missing or rows = NULL, all the rows in x are considered for the computation of the measures
na.rm: logical, whether to remove NA values from x before computation
...: further arguments to colSums2

A numerical vector containing the computed score for each column in x.

It is a wrapper to colSums2 function.
