Arguments

object

[Resampling]
mlr3 spatial resampling object of class ResamplingCV or ResamplingRepeatedCV.

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 ResamplingCV or ResamplingRepeatedCV.
