sframe_likert_scale_groups: Group a scale's Likert items for a combined diverging chart

In surveyframe: Survey Instrument Workflows

Group a scale's Likert items for a combined diverging chart

Description

Identifies which of an instrument's scales are eligible for one grouped diverging chart across their member items (sframe_plot_likert_scale()), the same way a "matrix" question's rows are grouped (sframe_plot_likert_matrix()): every member item is "likert" type and all share one choice set. Scales that mix response scales, that resolve to fewer than 2 qualifying items, or whose choice set cannot be found are left out and fall back to one chart per item in the report's Response distributions section.

Usage

sframe_likert_scale_groups(instrument)

Arguments

instrument

An sframe object.

Value

A named list, one entry per eligible scale (named by scale id), each a list with scale_id, title (the scale's label), items (the member item objects, in scale order), and choice_set (the shared choice set object). Empty list if no scale qualifies.
