autoplot() uses ggplot2 to draw plots as the ones produced by terra::plot()/terra::plotRGB() in a single command.

Usage

# S3 method for SpatRaster
autoplot(
  object,
  ...,
  rgb = NULL,
  use_coltab = NULL,
  facets = NULL,
  nrow = NULL,
  ncol = 2
)

# S3 method for SpatVector
autoplot(object, ...)

Arguments

object

A SpatRaster created with terra::rast() or a SpatVector created with terra::vect().

...

other arguments passed to geom_spatraster(), geom_spatraster_rgb() or geom_spatvector().

rgb

Logical. Should be plotted as a RGB image? If NULL (the default) autoplot.SpatRaster() would try to guess.

use_coltab

Logical. Should be plotted with the corresponding terra::coltab()? If NULL (the default) autoplot.SpatRaster() would try to guess. See also scale_fill_coltab().

facets

Logical. Should facets be displayed? If NULL (the default) autoplot.SpatRaster() would try to guess.

nrow, ncol

Number of rows and columns on the facet.

Value

A ggplot2 layer

Details

Implementation of ggplot2::autoplot().

Methods

Implementation of the generic ggplot2::autoplot() function.

SpatVector

Uses geom_spatvector(). Labels can be placed with geom_spatvector_text() or geom_spatvector_label()

Examples

# \donttest{

file_path <- system.file("extdata/cyl_temp.tif", package = "tidyterra")

library(terra)
temp <- rast(file_path)

library(ggplot2)
autoplot(temp)



# With a tile

tile <- system.file("extdata/cyl_tile.tif", package = "tidyterra") %>%
  rast()

autoplot(tile)


# With coltabs

ctab <- system.file("extdata/cyl_era.tif", package = "tidyterra") %>%
  rast()

autoplot(ctab)


#  With vectors
v <- vect(system.file("extdata/cyl.gpkg", package = "tidyterra"))
autoplot(v)


v %>% autoplot(aes(fill = cpro)) +
  geom_spatvector_text(aes(label = iso2)) +
  coord_sf(crs = 25829)

# }
