rowRanges: Gets the range of values in each row (column) of a matrix

In matrixStats: Methods that apply to rows and columns of a matrix

Description

Gets the range of values in each row (column) of a matrix.

Usage

  rowRanges(x, na.rm=FALSE, ...)
  colRanges(x, na.rm=FALSE, ...)
  rowMins(x, na.rm=FALSE, ...)
  colMins(x, na.rm=FALSE, ...)
  rowMaxs(x, na.rm=FALSE, ...)
  colMaxs(x, na.rm=FALSE, ...)

Arguments

x	A numeric NxK matrix.
na.rm	If TRUE, NAs are excluded first, otherwise not.
...	Not used.

Details

The rowRanges() function uses the much faster rowOrderStats() if there are no missing values.

Value

rowRanges() (colRanges()) returns a numeric Nx2 (Kx2) matrix, where N (K) is the number of rows (columns) for which the ranges are calculated.

rowMins()/rowMaxs() (colMins()/colMaxs()) returns a numeric vector of length N (K).
