Plot the allocation search for one budget — plot

Shows how the allocation evolved over the bisection on lambda, as a stacked area of allocations above a panel tracking lambda and its bracketing interval.

Usage

plot_iterations(
  adf,
  K_to_plot = NULL,
  itnum = NULL,
  num_targets_to_color = 6,
  target_palette = (scales::viridis_pal())(num_targets_to_color + 1)
)

Arguments

adf: an allocated object; see allocate().
K_to_plot: the budget whose search to show. Required unless adf has a single row.
itnum: how many iterations to show. Defaults to all of them.
num_targets_to_color: how many of the largest targets to colour individually; the rest are pooled into "other".
target_palette: colours for the individually coloured targets.

Value

A patchwork::patchwork object stacking the two panels.

Examples

fc <- add_pdqr_funs(
  tibble::tibble(
    target_names = c("a", "b", "c"), dist = "norm",
    mean = c(5, 8, 12), sd = c(1, 2, 3)
  ),
  types = c("p", "q")
)
plot_iterations(allocate(fc, K = 20, alpha = 0.9))
