Combine variables into one categorical variable

Description

Combine chosen variables of any class by concatenating them into one factor variable, and returns the result along with tidyverse code used to generate it.

Usage

  vars,
  sep = ":",
  name = NULL,
  keep_empty = FALSE,
  keep_na = TRUE
)

Arguments

data	a dataframe with the columns to be combined
vars	a character vector of the variables to be combined
sep	a character string to separate the levels
name	a name for the new variable
keep_empty	logical, if FALSE empty level combinations are removed from the factor
keep_na	logical, if TRUE the <NA> in the factors or NA in the characters will turn in a level "(Missing)"; otherwise, the resulting entries will return <NA>
