Exercise

Saving a tmap plot

Saving tmap plots is easy with the tmap_save() function. The first argument, tm, is the plot to save, and the second, filename, is the file to save it to. If you leave tm unspecified, the last tmap plot printed will be saved.

The extension of the file name specifies the file type, for example .png or .pdf for static plots. One really neat thing about tmap is that you can save an interactive version which leverages the leaflet package. To get an interactive version, use tmap_save() but use the file name extension .html.
