matrixStats (version 0.60.0)

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

Arguments

x

An NxK matrix or, if dim. is specified, an N * K vector.

rows

A vector indicating subset of rows to operate over. If NULL, no subsetting is done.

cols

A vector indicating subset of columns to operate over. If NULL, no subsetting is done.

na.rm

If TRUE, missing values are excluded.

dim.

An integer vector of length two specifying the dimension of x, also when not a matrix. Comment: The reason for this argument being named with a period at the end is purely technical (we get a run-time error if we try to name it dim).

...

Not used.

useNames

If NA, the default behavior of the function about naming support is remained. If FALSE, no naming support is done. Else if TRUE, names attributes of result are set.

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).
