Presence-absence Analysis by Cross Tabulation

Description

This function makes a cross-tabulation of two variables after transforming the first variable to presence-absence and then returns results of chisq.test.

Usage

crosstabanalysis(x,variable,factor)

Arguments

x	Data set that contains the variables "variable" and "factor".
variable	Variable to be transformed in presence-absence in the resulting cross-tabulation.
factor	Variable to be used for the cross-tabulation together with the transformed variable.

Value
