explore_trace_search: Plot the count in each iteration

In ferrn: Facilitate Exploration of touRR optimisatioN

Plot the count in each iteration

Description

Plot the count in each iteration

Usage

explore_trace_search(
  dt,
  iter = NULL,
  color = NULL,
  cutoff = 15,
  extend_lower = 0.95,
  ...
)

Arguments

dt	a data object collected by the projection pursuit guided tour optimisation in tourr
iter	the variable to be plotted on the x-axis
color	the variable to be coloured by
cutoff	numeric; if the number of searches in one iteration is smaller than cutoff, a point geom, rather than boxplot geom, will be used.
extend_lower	a numeric for extending the y-axis to display text labels
...	arguments passed into geom_label_repel() for displaying text labels

Value

a ggplot object for diagnosing how many points the optimiser(s) have searched
