autoplot.ResamplingSptCVCluto: Visualization Functions for SptCV Cluto Methods.

Description

Generic S3 plot() and autoplot() (ggplot2) methods to visualize mlr3 spatiotemporal resampling objects.

Usage

# S3 method for ResamplingSptCVCluto
autoplot(
  object,
  task,
  fold_id = NULL,
  plot_as_grid = TRUE,
  train_color = "#0072B5",
  test_color = "#E18727",
  tickformat_date = "%Y-%m",
  nticks_x = 3,
  nticks_y = 3,
  point_size = 3,
  axis_label_fontsize = 11,
  ...
)
# S3 method for ResamplingRepeatedSptCVCluto
autoplot(
  object,
  task,
  fold_id = NULL,
  repeats_id = 1,
  plot_as_grid = TRUE,
  train_color = "#0072B5",
  test_color = "#E18727",
  ...
)
# S3 method for ResamplingSptCVCluto
plot(x, ...)
# S3 method for ResamplingRepeatedSptCVCluto
plot(x, ...)

Arguments

object

[Resampling] mlr3 spatial resampling object of class ResamplingSptCVCluto or ResamplingRepeatedSptCVCluto.

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.

tickformat_date

[character] Date format for z-axis.

nticks_x

[integer] Number of x axis breaks. Only applies to SptCVCluto.

nticks_y

[integer] Number of y axis breaks. Only applies to SptCVCluto.

point_size

[numeric] Point size of markers.

axis_label_fontsize

[integer] Font size of axis labels.

...

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 ResamplingSptCVCluto or ResamplingRepeatedSptCVCluto.
