Description Usage Arguments Value Note See Also Examples

Converts a Move or MoveStack object from the move package to a LoCoH-xy object

move.lxy(move.obj, use.utm = FALSE, xcoord = NULL, ycoord = NULL,
  proj = NULL, anv.flds = NULL, ptid = NULL, del.dup.xyt = TRUE,
  dup.dt.check = TRUE, dt.int.round.to = 0.1, tau.diff.max = 0.02,
  req.id = TRUE, warn.latlong = TRUE, status = TRUE)

`move.obj`	A object of class Move or MoveStack.
`use.utm`	Import UTM coordinates if found and all points fall within the same UTM zone (T/F).
`xcoord`	The name of a field in the data table for the x-coordinates. If NULL, the default coordinates will be used.
`ycoord`	The name of a field in the data table for the y-coordinates. If NULL, the default coordinates will be used.
`proj`	Projection object of class `CRS-class`. Used only to specify the coordinate system when the coordinates being imported are coming from the data table
`anv.flds`	The name of field(s) in the Move object data table that will be imported as ancillary variables. Can also be 'all'.
`ptid`	The name of a numeric field in the Move object data table containing unique numeric values for each point. If NULL new point id values will be created.
`del.dup.xyt`	Whether to delete duplicate rows with the same x, y, dt, and id value (T/F).
`dup.dt.check`	Whether to check to make sure there are no duplicate date values for the same id.
`dt.int.round.to`	The proportion of the median sampling frequency that time intervals will be rounded to when computing the frequency table of sampling intervals (no change is made to the time stamps).
`tau.diff.max`	The maximum deviation from tau (expressed as a proportion of tau) that a point-to-point time difference must fall within for the point-to-point distance to be included in the calculation of the median step length.
`req.id`	Require a value for id (T/F).
`warn.latlong`	Show a warning message if it detects coordinates may be in latitude-longitude (T/F).
`status`	Show status messages (T/F).

A LoCoH-xy object

Move and MoveStack are formal classes from the Move package for storage of movement data for a single (Move) or multiple (MoveStack) indviduals. move.lxy will convert these objects to LoCoH-xy objects. To import the attribute data associated with each point (termed ancillary variables in T-LoCoH), set anv.flds to the names of the field(s) you wish to import (or anv.flds="all"). Note that the Move and MoveStack classes store a lot more metadata than LoCoH-xy objects, including unused records, which are not supported by the LoCoH-xy data class and are not imported.
