sim: Simulate Draws from a Sample Space

In prob: Elementary Probability on Finite Sample Spaces

Description

Simulates the experiment of drawing from a sample space.

Usage

sim(x, ...)

## Default S3 method:
sim(x, ntrials, ...)

## S3 method for class 'ps'
sim(x, ntrials, ...)

Arguments

x	a probability space or a subset of one.
ntrials	number of times to repeat the experiment.
...	further arguments to be passed to or from other methods.

Details

The sim() function is a wrapper for sample(), except that it strips the probs component from the result and (if x is a data frame) renames the rownames of the data frame consecutively from 1:ntrials.

Value

A data frame if space is a data frame, or a list if space is of class ps.
