calculate_co_occurrences: Calculate code co-occurrences in annotations

In textAnnotatoR: Interactive Text Annotation Tool with 'shiny' GUI

Calculate code co-occurrences in annotations

Description

Analyzes text annotations to identify and count instances where different codes overlap or co-occur in the same text regions. Handles edge cases and provides error-safe operation.

Usage

calculate_co_occurrences(annotations)

Arguments

annotations

Data frame containing annotations with columns: start: numeric, starting position of annotation end: numeric, ending position of annotation code: character, code identifier

Details

Co-occurrences are identified by finding overlapping text regions between different code annotations. The function sorts annotations by position and checks for overlaps between each pair of annotations.

Value

Table object containing frequencies of code pairs that co-occur, with code pair names as "code1 & code2"
