Dear Dr. Rowcliffe,
for my dataset, the following lines work properly.
pkg <- read_camtrap_dp("./datapackage.json", media = TRUE)
sub <- subset_deployments(pkg, start >= as_datetime("2023-02-01") &
start <= as_datetime("2023-02-28"))But the following lines do not. The difference lies with the media statement.
pkg <- read_camtrap_dp("./datapackage.json", media = FALSE)
sub <- subset_deployments(pkg, start >= as_datetime("2023-02-01") &
start <= as_datetime("2023-02-28"))The error reads:
Error in UseMethod("filter") : no applicable method for 'filter' applied to an object of class "NULL"
Thus the presence of media seems mandatory for the function to work, when in fact it is optional. This isn't a critical error (as I can read in media), but it might lead other users to frustatingly seek for an explanation. So it would seem best to mention this in the Help file, or fix it.
I still love these functions, as they come in very handy!
