chisq: Chi-square test by simulation for a two-way table
Description
Calculate a p-value for a chi-square test by Monte Carlo simulation.
Usage
chisq(tab, n.sim = 1000)
Value
A single number: the P-value testing independence of rows and columns
in the table.
Arguments
tab
A matrix of counts.
n.sim
Number of samples of permuted tables to consider.
Details
This is like the function stats::chisq.test(), but
calculates an approximate P-value rather than refering to
asymptotics. This will be better for large, sparse tables.
