apply.factor.grouping: Apply groupings to new data

In konstantin-kotochigov/ML-UTILS: Kostyan's functions

Description

Groups factor values according to mapping generated as an output of a function group.factor. Thus the same grouping can be applied to new datasets. Now it uses dataset itself as a mapping, which is not very efficient. In future releases a proper mapping will be generated and used.

Usage

apply.factor.grouping(data, variables, new.data, other.factor = "other")

Arguments

data	data with already grouped data
variables	factors to analyze
new.data	new data frame with factor variables to convert
other.factor	name of the "other" group

Value

new data frame with added columns named group.X (where X is variable name)

Examples

new.df <- apply.factor.grouping(df, c('var1','var2','var3'), new.df)
