nsamples: Number of samples

In softclassval: Soft Classification Performance Measures

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

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

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