Plot the projection from the optimisation data collected from projection pursuit

Usage

plot_projection(
  dt,
  data,
  id = NULL,
  cols = NULL,
  label = TRUE,
  animate_along = NULL,
  keep = 0.2
)

compute_projection(dt, data, id = NULL, cols = NULL)

Arguments

dt

a data object collected by the projection pursuit guided tour optimisation in tourr

data

the original data

id

the grouping variable

cols

additional columns to include in the plot

label

logical, whether to label each panel by its index value

animate_along

the variable to animate along

keep

Value

a ggplot object

Examples

library(dplyr)
holes_2d_jellyfish |>
  filter(loop == 1, tries %in% seq(1, 50, 5)) |>
  plot_projection(data = boa6)

if (FALSE) { # \dontrun{
library(dplyr)
# track the first jellyfish (loop == 1)
holes_2d_jellyfish |>
  filter(loop == 1) |>
  plot_projection(data = boa6, animate_along = tries, id = loop)
} # }
