photo_group | R Documentation |
This function allows you to group photos, by time or a combination of time and location.
If date_time_cut
values are taken (times in which to break the photos)
time alone will be used to break-up the photos.
If not, you can simply request a number of breaks with n_groups
.
photo_group(photo, n_groups = 3, date_time_cut = NULL, cluster_string = "Latitude$|Longitude$|date_time")
