Description

This function attempts to be flexible, but may not cover all usage cases. See the examples for known-supported usage cases.

Usage

  widenames(varnames,
    varlevels = vector("list", length(varnames)))

Arguments

varnames	This can be a vector of character values, a list of character values, or a data.frame of factors.
varlevels	This can be a vector of numeric (specifying the number of levels) or a list of character (specifying the factor levels) when varnames is a vector of characters. When varnames is a data.frame, it must be a list specifying either the numeric id of the desired factor levels or the names of the factors themselves.
