Plot the count in each iteration
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
