Returns a compact role-distribution table and per-variable breakdown, and prints a readable synopsis to the console.
Usage
# S3 method for class 'modality_gravity'
summary(object, ...)Arguments
- object
A data frame returned by
modality_gravity.- ...
Ignored.
Value
Invisibly returns a list with elements:
- role_counts
Named integer vector of attractor/neutral/satellite counts.
- by_variable
Data frame with one row per variable showing the dominant role and mean
delta_mgiacross its modalities.- top_attractor
Single-row data frame: modality with highest
delta_mgi.- top_satellite
Single-row data frame: modality with lowest
delta_mgi.- spearman_strength
Spearman correlation between
strengthanddelta_mgi.
Examples
data(survey_health)
mg <- build_modality_graph(survey_health)
mg <- prune_modality_edges(mg, min_weight = 0.10, max_p = 0.05)
grav <- modality_gravity(mg)
