Feature Stability - EC Consistency Facet Plot

Display a facet of plots where each subpanel is associated with a feature set and illustrates the distribution of the EC consistency score over the UMAP embedding.

plot_feature_stability_ecs_facet(
  feature_object_list,
  n_facet_cols = 3,
  point_size = 0.3
)

Arguments

feature_object_list

An object or a concatenation of objects returned by the `get_feature_stability` method

n_facet_cols

The number of facet's columns.

point_size

The size of the points displayed on the plot.

Value

A ggplot2 object
