file_drawer: Manage the ggmap file drawer.

In ggmap: Spatial Visualization with ggplot2

Manage the ggmap file drawer.

Description

To avoid downloading the same maps again and again, ggmap uses a "file drawer" to store the maps you've downloaded. By default, they will be stored in a session specific temporary directory which will be deleted each time you quit R. If you want them to persist across sessions, set the global option "ggmap.file_drawer".

Usage

file_drawer(...)

Examples

## Not run:  if server is unresponsive, R check will fail

file_drawer()
dir(file_drawer())

# The first time you run this, the tiles are downloaded from the server
map <- get_stadiamap()
# The second time, the local cache is used so it's much faster
map <- get_stadiamap()

dir(file_drawer())


## End(Not run)
