autoplot.spatial_initial_split: Create a ggplot for a spatial initial rsplit.

Description

This method provides a good visualization method for a spatial initial rsplit.

Usage

# S3 method for spatial_initial_split
autoplot(object, ..., alpha = 0.6)

Value

A ggplot object with each fold assigned a color, made using ggplot2::geom_sf().

Arguments

object

A spatial_initial_rsplit object. Note that only resamples made from sf objects create spatial_initial_rsplit objects; this function will not work for resamples made with non-spatial tibbles or data.frames.

...

Options passed to ggplot2::geom_sf().

alpha

Opacity, passed to ggplot2::geom_sf(). Values of alpha range from 0 to 1, with lower values corresponding to more transparent colors.

Details

This plot method is a wrapper around the standard spatial_rsplit method, but it re-labels the folds as Testing and Training following the convention for a standard initial_split object

Examples

set.seed(123)
block_initial <- spatial_initial_split(boston_canopy,
  prop = 1 / 5, spatial_block_cv
)
autoplot(block_initial)
