nsamples: Number of samples

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

Value

number of samples in each group (rows) for each class (columns) and all further dimensions of ref.

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.

Examples

ref <- softclassval:::ref
ref
nsamples (ref)
nsamples (ref, hard.operator = TRUE)
