as.telemetry: Import, coerce, and summarize MoveBank data
Description
Functions to import MoveBank csv files or data.frame objects, coerce them into telemetry objects, and summarize them.Usage
as.telemetry(CSV,timezone="GMT",projection=NULL,...)
## S3 method for class 'telemetry':
summary(object,...)
Arguments
CSV
The file name of the MoveBank csv file or a raw data.frame object from previously read MoveBank data.
projection
Optional PROJ.4 projection argument to be fed to project. ...
Optional arguments to be fed to read.csv. object
telemetry object to summarize.
Value
as.telemetry returns a single telemetry object or list of telemetry objects if multiple animals are identified.
Details
If no projection argument is specified, a two-point equidistant projection is calculated that should be good for most range resident and migratory species.
Global migrations that are not relatively geodesic (locally straight) will probably suffer distortion.
The current MoveBank columns used are individual.local.identifier, timestamp, location.long, location.lat.
In the future, we will be supporting more GPS and ARGOS columns, including speed, heading, error classification, etc.
