Description
Performs a sampling version of Fisher's exact test for a two-way contingency table.
Usage
fisher(tab, n.sim = 1000)
Arguments
tab |
A matrix of counts. |
n.sim |
Number of samples of permuted tables to consider. |
Details
This is like the function stats::fisher.test()
, but
calculates an approximate P-value rather than performing a complete
enumeration. This will be better for large, sparse tables.
Value
A single number: the P-value testing independence of rows and columns in the table.
