add_categorical_event: Create Classification Variable Based On Window

In outcomesinsights/jigsaw_r: Tools for Working With Observational Data

Description

Takes a categorical (string) variable in the events file and classifies a person based on all available values in a window of time before the person's index date (from cohort file). Windows must be negative (i.e., before index date). This is useful for identifying whether a value has occurred in a window of time. For example, was the person classified as a smoker during the last 3 years?

Arguments

varname	event name to check for values
check_value	The character value or vector to compare against (e.g. c("yes", "maybe"))
days	Size of window before the index date (from cohort file) in days
