In Bioconductor/MatrixGenerics: S4 Generic Summary Statistic Functions that Operate on Matrix-Like Objects

Calculates the interquartile range of the difference between each element of a row (column) of a matrix-like object

Description

Calculates the interquartile range of the difference between each element of a row (column) of a matrix-like object.

Usage

rowIQRDiffs(x, rows = NULL, cols = NULL, na.rm = FALSE, diff = 1L,
  trim = 0, ..., useNames = TRUE)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
rowIQRDiffs(x, rows = NULL,
  cols = NULL, na.rm = FALSE, diff = 1L, trim = 0, ...,
  useNames = TRUE)

## S4 method for signature 'ANY'
rowIQRDiffs(x, rows = NULL, cols = NULL, na.rm = FALSE,
  diff = 1L, trim = 0, ..., useNames = TRUE)

colIQRDiffs(x, rows = NULL, cols = NULL, na.rm = FALSE, diff = 1L,
  trim = 0, ..., useNames = TRUE)

## S4 method for signature 'matrix_OR_array_OR_table_OR_numeric'
colIQRDiffs(x, rows = NULL,
  cols = NULL, na.rm = FALSE, diff = 1L, trim = 0, ...,
  useNames = TRUE)

## S4 method for signature 'ANY'
colIQRDiffs(x, rows = NULL, cols = NULL, na.rm = FALSE,
  diff = 1L, trim = 0, ..., useNames = TRUE)

Arguments

x	An NxK matrix-like object.
rows, cols	A vector indicating the subset of rows (and/or columns) to operate over. If NULL, no subsetting is done.
na.rm	If TRUE, missing values (NA or NaN) are omitted from the calculations.
diff	An integer specifying the order of difference.
trim	A double in [0,1/2] specifying the fraction of observations to be trimmed from each end of (sorted) x before estimation.
...	Additional arguments passed to specific methods.
useNames	If TRUE (default), names attributes of result are set. Else if FALSE, no naming support is done.

Details

The S4 methods for x of type matrix, array, table, or numeric call matrixStats::rowIQRDiffs / matrixStats::colIQRDiffs.

Value

Returns a numeric vector of length N (K).

Examples

mat <- matrix(rnorm(15), nrow = 5, ncol = 3)
mat[2, 1] <- NA
mat[3, 3] <- Inf
mat[4, 1] <- 0

print(mat)

rowIQRDiffs(mat)
colIQRDiffs(mat)
