Combine Codes

Description

Combine all occurrences of codes into a new code.

Usage

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

Arguments

x2long.obj

An object from cm_range2long, cm_time2long or cm_df2long.

combine.code.list

A list of named character vectors of at least two code column names to combine

rm.var

Name of the repeated measures column.

Value

Returns a dataframe with combined occurrences of supplied overlapping codes added.

Note

The code column must be named "code" and your start and end columns must be named "start" and "end".
