Description

plots a uncertainty cube

Usage

# S3 method for uncertainty_cube
plot(
  x,
  ...,
  tile = x[["tile"]][[1]],
  roi = NULL,
  palette = "RdYlGn",
  rev = TRUE,
  scale = 1,
  first_quantile = 0.02,
  last_quantile = 0.98,
  max_cog_size = 1024,
  legend_position = "inside"
)

Value

A plot object produced showing the uncertainty associated to each classified pixel.

Arguments

x

Object of class "probs_image".

...

Further specifications for plot.

tile

roi

Spatial extent to plot in WGS 84 - named vector with either (lon_min, lon_max, lat_min, lat_max) or (xmin, xmax, ymin, ymax)

palette

An RColorBrewer palette

rev

Reverse the color order in the palette?

scale

Scale to plot map (0.4 to 1.0)

first_quantile

First quantile for stretching images

last_quantile
