Plot FDA Selection Results

Plots feature-, group-, interval-, and basis-level summaries derived from selection_map(). The available views depend on the fitted object:

Usage

# S3 method for class 'fda_stability_selection'
plot(
  x,
  type = c("feature", "group", "interval", "basis"),
  value = c("group", "mean", "max"),
  facet = c("none", "predictor"),
  palette = selection_palette(),
  show_legend = TRUE,
  legend_title = NULL,
  legend_n_ticks = 3L,
  legend_digits = 2L,
  legend_cex = 0.75,
  cutoff = x$cutoff,
  ...
)

# S3 method for class 'selectboost_fda_result'
plot(
  x,
  type = c("feature", "group", "basis"),
  value = c("max", "mean"),
  palette = selection_palette(),
  show_legend = TRUE,
  legend_title = NULL,
  legend_n_ticks = 3L,
  legend_digits = 2L,
  legend_cex = 0.75,
  c0 = NULL,
  ...
)

Arguments

x

An object returned by stability_selection_fda(), interval_stability_selection(), fit_stability(), selectboost_fda(), or fit_selectboost().

type

Summary view to plot. Stability-selection fits support "feature", "group", "interval", and "basis". SelectBoost fits support "feature", "group", and "basis".

value

Quantity summarized in group, interval, and basis views. Stability-selection fits accept "group", "mean", and "max". SelectBoost fits accept "mean" and "max".

facet

Faceting mode for interval heatmaps. Currently only type = "interval" uses this argument.

palette

Vector of colors used for heatmaps.

show_legend

Logical; should heatmap views draw a legend?

legend_title

Optional legend title for heatmap views. By default an informative title is chosen from type and value.

legend_n_ticks

Approximate number of tick marks used in the heatmap legend.

legend_digits

Number of significant digits used for heatmap legend labels.

legend_cex

Character expansion used for heatmap legend text.

cutoff

Stability threshold. Only used for fda_stability_selection objects.

...

Additional graphical parameters passed to bar-plot-based views.

c0

Optional SelectBoost correlation threshold. When omitted, SelectBoost heatmaps are drawn across all available c0 values.

Value

Invisibly returns the helper output used to build the plot.

Details

• fda_stability_selection supports type = "feature", "group", "interval", and "basis".

• selectboost_fda_result supports type = "feature", "group", and "basis".

Heatmap-based views are used for interval summaries and for SelectBoost summaries over multiple c0 values. Bar-plot views are used otherwise.
