multiVarFreq: Generate a table collapsing frequencies of multiple variables

In userfriendlyscience: Quantitative Analysis Made Accessible

Description

This function can be used to efficiently combine the frequencies of variables with the same possible values. The frequencies are collapsed into a table with the variable names as row names and the possible values as column (variable) names.

Usage

multiVarFreq(data,
             items = NULL,
             labels = NULL,
             sortByMean = TRUE)

Arguments

data	The dataframe containing the variables.
items	The variable names.
labels	Labels can be provided which will be set as row names when provided.
sortByMean	Whether to sort the rows by mean value for each variable (only sensible if the possible values are numeric).

Value

The resulting dataframe, but with class 'multiVarFreq' prepended to allow pretty printing.
