light_recode: Recode Factor Columns

Description

Recodes factor levels of columns in data slots of an object of class light.

Usage

light_recode(x, ...)
# S3 method for default
light_recode(x, ...)
# S3 method for light
light_recode(x, what, levels, labels, ...)

Arguments

x

An object of class light.

...

Further arguments passed to factor.

what

Column identifier in x (not column name) to be recoded, e.g. "type_name", "label_name".

levels

Current levels/values of type_name column (in desired order).

labels

New levels of type_name column in same order as levels.

Value

x with new factor levels of type_name column.

Methods (by class)
