cm_code.overlap: Find Co-occurrence Between Codes

Description

Combine co-occurrences of codes into a new code.

Usage

cm_code.overlap(x2long.obj, overlap.code.list, rm.var = NULL)

Value

Returns a dataframe with co-occurrences of supplied overlapping codes added.

Arguments

x2long.obj

An object from cm_range2long, cm_time2long or cm_df2long.

overlap.code.list

A list of named character vectors of at least two code column names to aggregate co-occurrences.

rm.var

Name of the repeated measures column.
