In prob: Elementary Probability on Finite Sample Spaces

Description

Sets up a sample space for the experiment of rolling a die repeatedly.

Usage

rolldie(times, nsides = 6, makespace = FALSE)

Arguments

times	number of rolls.
nsides	number of sides on the die.
makespace	logical.

Details

The function uses expand.grid() to generate all possible rolls resulting from the experiment of rolling a die. Sides on the die are 1:nsides. Columns of the data frame are called X1, X2, up to Xtimes
