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

Arguments

x

An NxK matrix-like object.

rows

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

cols

A vector indicating the 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.

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.

Details

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

Value

Returns a numeric vector of length N (K).
