Create a (ggplot2) raster layer

Source: R/inset_raster.R
inset_raster.Rd

This is a special version of ggplot2::annotation_raster for use with ggmap. (It simply removes the requirement for cartesian coordinates.) The only difference between inset_raster() and inset_ggmap() is their arguments. inset_ggmap() is simply a wrapper of inset_raster() with xmin, ..., ymax arguments equal to the map's bounding box.

Usage

inset_raster(raster, xmin, xmax, ymin, ymax, interpolate = TRUE)

inset_ggmap(ggmap)

Arguments

raster

raster object to display

xmin, xmax

x location (in data coordinates) giving horizontal location of raster

ymin, ymax

y location (in data coordinates) giving vertical location of raster

interpolate

interpolate the raster? (i.e. antialiasing)

ggmap

a ggmap object, see get_map()

Examples


if (FALSE)  # save cran check time

bbox <- c(left = -97.1268, bottom = 31.536245, right = -97.099334, top = 31.559652)

terrain_map <- get_stadiamap(bbox, zoom = 14, maptype = "stamen_terrain_background", color = "bw")
#> Error in eval(expr, envir, enclos): object 'bbox' not found
ggmap(terrain_map)
#> Error in eval(expr, envir, enclos): object 'terrain_map' not found

lines_map <- get_stadiamap(bbox, zoom = 14, maptype = "stamen_toner_lines")
#> Error in eval(expr, envir, enclos): object 'bbox' not found
ggmap(lines_map)
#> Error in eval(expr, envir, enclos): object 'lines_map' not found

ggmap(terrain_map) +
  inset_ggmap(lines_map)
#> Error in eval(expr, envir, enclos): object 'terrain_map' not found
