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

Description

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

Usage

rowRanges(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)
  colRanges(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)
  rowMins(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)
  colMins(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)
  rowMaxs(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)
  colMaxs(x, rows=NULL, cols=NULL, na.rm=FALSE, dim.=dim(x), ...)

Arguments

x

A numeric NxK matrix.

rows, cols

A vector indicating subset of rows (and/or columns) to operate over. If NULL, no subsetting is done.

na.rm

If TRUE, NAs are excluded first, otherwise not.

dim.

An integer vector of length two specifying the dimension of x, also when not a matrix.

...

Not used.

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).
