Why, when creating a ppp object, are all my co-ordinates omitted?
For my masters project, I have data frame of boating vessel positions (VesPos – lon,lat), time (fixed_timestamp_utc, years, quarters) and Vessel ID (vessel_id). I also have a multi-polygon object of a ICES designation area “6a” (ICES_6a) as my spatial window for edge-correction. My data runs across multiple years, some which do not have data for every quarter (specifically the first and last year).
