| compare_flags | Joins and reformats two animal data frames for the purpose of flag comparison |
| compare_summarise_daily | Compares two animal datasets and calculates daily summary statistics by GPS GPS, date, lat, long, course, distance, rate, elevation column names should match. |
| compare_summarise_data | Compares two animal data frames and calculates summary statistics. GPS, date, lat, long, course, distance, rate, elevation column names should match. |
| deg_to_dec | Helper function for cleaning Columbus P-1 datasets. Given lat or long coords in degrees and a direction, convert to decimal. |
