This function adds timestamps to animation frames created with frames_spatial
.

x | numeric, optional, position of timestamps on the x scale. By default, timestamps will be displayed in the top center. |
y | numeric, optional, position of timestamps on the y scale. |
... | optional, arguments passed to |
verbose | logical, if |
