Visualization Functions for SpCV Coords Methods.

Generic S3 plot() and autoplot() (ggplot2) methods.

# S3 method for ResamplingSpCVCoords
autoplot(
  object,
  task,
  fold_id = NULL,
  plot_as_grid = TRUE,
  train_color = "#0072B5",
  test_color = "#E18727",
  crs = NULL,
  ...
)

# S3 method for ResamplingRepeatedSpCVCoords
autoplot(
  object,
  task,
  fold_id = NULL,
  repeats_id = 1,
  plot_as_grid = TRUE,
  train_color = "#0072B5",
  test_color = "#E18727",
  crs = NULL,
  ...
)

# S3 method for ResamplingSpCVCoords
plot(x, ...)

# S3 method for ResamplingRepeatedSpCVCoords
plot(x, ...)

Arguments

object	[Resampling] mlr3 spatial resampling object of class ResamplingSpCVCoords or ResamplingRepeatedSpCVCoords.
task	[TaskClassifST]/[TaskRegrST] mlr3 task object.
fold_id	[numeric] Fold IDs to plot.
plot_as_grid	[logical(1)] Should a gridded plot using via patchwork be created? If FALSE a list with of ggplot2 objects is returned. Only applies if a numeric vector is passed to argument fold_id.
train_color	[character(1)] The color to use for the training set observations.
test_color	[character(1)] The color to use for the test set observations.
crs	[character] EPSG code of the CRS for x and y axes.
...	Passed to geom_sf(). Helpful for adjusting point sizes and shapes.
repeats_id	[numeric] Repetition ID to plot.
x	[Resampling] mlr3 spatial resampling object of class ResamplingSpCVCoords or ResamplingRepeatedSpCVCoords.
