autoplot.MAPraster: Quickly visualise Rasters downloaded from MAP

Description

autoplot.MAPraster creates a map of all rasters in a MAPraster object and displays these in a grid.

Usage

# S3 method for MAPraster
autoplot(
  object,
  ...,
  shp_df = NULL,
  legend_title = "",
  plot_titles = TRUE,
  fill_scale_transform = "identity",
  fill_colour_palette = "RdYlBu",
  printed = TRUE
)

Value

autoplot.MAPraster returns a list of plots (gg objects) for each supplied raster.

Arguments

object

MAPraster object to be visualised.
