nsamples: Number of samples
In softclassval: Soft Classification Performance Measures

Count number of samples

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

`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

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.

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