Append Group

Description

Creates a new category level by combining existing levels. Appends new observations to dataset.

Usage

append_group(df, group_var, formula, drop = FALSE)

Arguments

df	data.frame or data.table
group_var	unquoted variable name of categorical variable
formula	a formula, LHS ~ RHS. The LHS side denotes the new level label. The RHS denotes the categories to be combined. For example: `Species starting with V` ~ versicolor + verginica.
drop	TRUE/FALSE. If FALSE, the resulting dataframe will include the original data plus observations with the new category level (rows will be duplicated). If TRUE, the command will eliminate rows in the original data with the old category levels (rows are not duplicated). Default is FALSE.
