This is a precomputed ggmap for running_example.gpx, to avoid needing an
API key in vignettes, which get_ggmap_from_df() requires.
running_example_ggmapAn object of class ggmap (inherits from raster) with 1280 rows and 1280 columns.
This is the result of running:
running_file <- system.file(
  "extdata",
  "running_example.gpx",
  package = "activatr")
running_df <- parse_gpx(running_file)
running_example_ggmap <- get_ggmap_from_df(running_df)
after setting a valid API key.
