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.

probs

A numeric vector of J probabilities in [0, 1].

na.rm

If TRUE, NAs are excluded first, otherwise not.

type

An integer specifying the type of estimator. See stats::quantile(). for more details.

...

Additional arguments passed to specific methods.

drop

If TRUE a vector is returned if J == 1.

Details

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

Value

a numeric NxJ (KxJ) matrix, where N (K) is the number of rows (columns) for which the J values are calculated.
