Description

Count number of samples

Usage

nsamples(r = r, groups = NULL, operator = "prd", hard.operator)

Arguments

r

reference class labels with samples in rows.

groups

grouping variable for the averaging by rowsum. If NULL, all samples (rows) are averaged.

operator

the operator to be used

hard.operator

optional: a logical determining whether only hard samples should be counted

Details

Basically, the reference is summed up. For hard operators, the reference is hardened first: soft values, i.e. r in (0, 1) are set to NA.

Value
