Modify groupbyvars by adding or removing decode vars.

Source: R/ru_groupbyvars.R
ru_groupbyvars.Rd

Pass in a vector of group-by variables along with a vector of code/decode pairs to have decode variables added or removed.

Usage

ru_groupbyvars(groupbyvars, codedecodevarpairs, adddecode = TRUE)

Arguments

groupbyvars

Vector of group-by variables.

codedecodevarpairs

Specifies code and decode variable pairs. Those variables should be in parameter GROUPBYVARSNUMER. One variable in the pair will contain the code, which is used in counting and ordering, and the other will contain decode, which is used for presentation.

adddecode

Add decode variables (true) or remove (false).

Value

A data frame based on the incoming data frame but collapsed by groups with counts and percents added.
