Description Usage Arguments Value Examples

Generate a map image for a specified area or bounding box, by downloading tiles from https://www.mapbox.com/. Map is automatically saved in both .pdf and .png formats, by default in current working directory, or alternative location when mapname includes the full path.

ms_generate_map(
  bbox,
  max_tiles = 16L,
  mapname = NULL,
  bw = TRUE,
  style = "light",
  raster_brick = NULL
)

`bbox`	Either a string specifying the location, or a numeric bounding box as a single vector of (xmin, ymin, xmax, ymax), or a 2-by-2 matrix with columns of (min, max) and rows of (x, y), respectively.
`max_tiles`	Maximum number of tiles to use to create map
`mapname`	Name of map to be produced, optionally including full path. Extension will be ignored.
`bw`	If `FALSE`, print maps in colour, otherwise black-and-white. Note that the default `style = "light"` is monochrome, and that this parameter only has effect for `style` values of `"streets"` or `"outdoors"`.
`style`	The style of the map to be generated; one of 'light', 'streets', or 'outdoors', rendered in black and white. See https://docs.mapbox.com/api/maps/#styles/ for examples.
`raster_brick`	Instead of automatically downloading tiles within a given `bbox`, a pre-downloaded `raster::rasterBrick` object may be submitted and used to generate the `.pdf` and `.png` equivalents.

Invisibly returns a rasterBrick object from the raster package containing all data used to generate the map.
