Read data from a standard GLATOS detection (csv) file and return
a data.frame of class glatos_detections
.
read_glatos_detections(det_file, version = NULL)
det_file |
A character string with path and name of detection file in standard GLATOS format (*.csv). If only file name is given, then the file must be located in the working directory. File must be a standard GLATOS file (e.g., xxxxx_detectionsWithLocs_yyyymmdd_hhmmss.csv) submitted via GLATOSWeb Data Portal http://glatos.glos.us. |
version |
An optional character string with the glatos file version
number. If NULL (default value) then version will be determined by
evaluating file structure. The only allowed values currently are
|
Data are loaded using fread and timestamps are coerced to POSIXct using fastPOSIXct. All times must be in UTC timezone per GLATOS standard.
Column animal_id
is considered a required column by many
other functions in this package, so it will be created if any records are
NULL
. When created, it will be constructed from
transmitter_codespace
and transmitter_id
, separated by '-'.
A data.frame of class glatos_detections
