Arguments

object	[Resampling] mlr3 spatial resampling object of class ResamplingSptCVCstf or ResamplingRepeatedSptCVCstf.
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 only a list with all ggplot2 resamplings 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.
crs	[character] EPSG code of the CRS for x and y axes. If not set, EPSG 4326 (WGS84) is used.
nticks_x	[integer] Number of x axis breaks.
nticks_y	[integer] Number of y axis breaks.
point_size	[numeric] Point size of markers.
axis_label_fontsize	[integer] Font size of axis labels.
...	Not used.
repeats_id	[numeric] Repetition ID to plot.
x	[Resampling] mlr3 spatial resampling object of class ResamplingSptCVCstf or ResamplingRepeatedSptCVCstf.
