This function computes the *median* for each column in an input matrix. See the **Details** section below for further information.

Usage

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

Arguments

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
