Convert a Track Table to/from Other Formats

Description

The following methods will convert track tables to and from other common formats used for processing tracking and spatial data.

Usage

as_track(x, table = "df", ...)

## S3 method for class 'MoveStack'
as_track(x, table = "df", ...)

## S3 method for class 'Move'
as_track(x, table = "df", ...)

as_move(x, ...)

## S3 method for class 'track'
as_move(x, ...)

## S3 method for class 'SpatialPointsDataFrame'
as_track(x, table = "df", ...)

as_sp(x, ...)

## S3 method for class 'track'
as_sp(x, ...)

## S3 method for class 'ltraj'
as_track(x, table = "df", ...)

as_ltraj(x, ...)

## S3 method for class 'track'
as_ltraj(x, ...)

## S3 method for class 'telemetry'
as_track(x, table = "df", ...)

## S3 method for class 'list'
as_track(x, table = "df", ...)

as_telemetry(x, ...)

## S3 method for class 'track'
as_telemetry(x, ...)

## S3 method for class 'moveData'
as_track(x, table = "df", type = c("LL", "UTM"), ...)

as_moveHMM(x, ...)

## S3 method for class 'track'
as_moveHMM(x, ...)

Arguments

x	An object to convert.
table	A string indicating the class of the table on which the track table should be built. It can be a data.frame ("df", the default), a tibble ("tbl"), or a data.table ("dt").
...	Other parameters to be passed to: track_df, track_tbl or track_dt if as_track is used. moveVis::df2move if as_move is used. sp::SpatialPointsDataFrame if as_sp is used. adehabitatLT::as.ltraj if as_ltraj is used. ctmm::as.telemetry if as_telemetry is used. moveHMM::prepData if as_moveHMM is used.
type	For converting moveHMM::moveData to track table only, a character string indicating the type of coordinates stored in the moveHMM::moveData object: "LL" if longitude/latitude (default), "UTM" if easting/northing.

Value

The coordinates converted in the chosen format.

if (requireNamespace("adehabitatLT", quietly = TRUE)) {
  lt <- as_ltraj(short_tracks)
  as_track(lt)
}

if (requireNamespace("ctmm", quietly = TRUE)) {
  tl <- as_telemetry(short_tracks)

  hhm <- as_moveHMM(short_tracks, type = "LL")
  as_track(hhm)
}
