print.rvfactorR Documentation

Categorical Random Variables (Random Factors)

Description

Creates or tests for objects of type "rvfactor".

Usage

## S3 method for class 'rvfactor'
print(x, all.levels = FALSE, ...)

rvfactor(x, ...)

## Default S3 method:
rvfactor(x, levels = NULL, ...)

Arguments

x

object to be coerced or tested.

all.levels

logical; whether to print all levels or not (see below for details)

...

other arguments

levels

factor levels (labels for the levels)

Details

Internally random factors are integer-valued just like regular factors in R.

The number of levels to print when all.levels==FALSE can be set by rvpar(max.levels=...). By default this is set to 10.

Value

rvfactor: an rvfactor object.

is.rvfactor: TRUE or FALSE.

as.rv.rvfactor: an rv object.

as.rvfactor.rv: an rvfactor object.
