Create a heatmap of shared target use by pairs of interpreters

Create a heatmap of shared target use by pairs of interpreters

Usage

membership_target_pair_heatmap(data)

Arguments

data

A membership_tbl object containing membership data in long format, with columns for source, target, membership and interpreter values.

Value

A ggplot object representing the heatmap of shared target use by pairs of interpreters.

Details

Returns a heatmap of how often each pair of interpreters used the same target for the same source unit, for a single round of elicitation. Each tile shows the number of source units where both interpreters of a pair assigned membership to a target, with a colour gradient from light to dark teal for more source units. Empty tiles mean the pair never used that target for the same source unit. Rows with missing or zero membership are not counted as use. The plot helps to spot targets that pairs of interpreters agree or disagree on.

Future Enhancements

The function is designed to be flexible and can be extended in the future to include additional customization options. Users may filter by round of elicitation, show the number of source units where only one interpreter of a pair used a target, and specify theme options, colour palette, label aesthetics, axis labels, title and subtitle to tailor the plot to their specific needs.
