This function builds unique character string identifiers for all origins and destinations.
get_unique_ids( data, orig = TRUE, dest = TRUE, adm_start = NULL, adm_stop = NULL, name_class = "character" )
| data | generalized data frame described in |
|---|---|
| orig | logical indicating whether to include unique coordinates from origin locations (default=TRUE) |
| dest | logical indicating whether to include unique coordinates from destination locations (default=TRUE) |
| adm_start | highest administrative level to include in unique names (default = NULL, which uses highest observed in the data) |
| adm_stop | lowest administrative level to include in unique names (default = NULL, which uses lowest observed in the data) |
| name_class | character indicating whether unique names should be either a unique character string ( |
two column dataframe containing unique names
Other utility:
