cm_code.overlap: Find Co-occurrence Between Codes

In trinker/qdap: Bridging the Gap Between Qualitative Data and Quantitative Analysis

Description

Combine co-occurrences of codes into a new code.

Usage

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

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.

Value

Returns a dataframe with co-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".
