Arguments

data the data as a data frame
var a string naming the variable of interest in data
counts a string naming a variable in data containing counts, or NULL if each row represents a single observation
expected TRUE or FALSE (default), whether expected counts should be displayed
ratio a vector of numbers: the expected proportions

Returns

A results object containing:

results$props a table
results$tests a table

Tables can be converted to data frames with asDF or as.data.frame(). For example:

results$props$asDF

as.data.frame(results$props)
