lxy.reproject: Project or reproject coordinates

In tlocoh: Constructs homeranges and explores time use patterns from location data

Description

Project or reproject coordinates of a LoCoH-xy object

Usage

lxy.reproject(lxy, proj, dt.int.round.to = 0.1, tau.diff.max = 0.02,
  status = TRUE)

Arguments

lxy	A LoCoH-xy object
proj	Projection object of class CRS-class
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
status	Show status messages (T/F)

Details

This function will reproject the locations to a new coordinate system. In order for this to work,

• The coordinate system of the current locations must be recorded. To see the current coordinate system, run summary.locoh.lxy. To add projection information (which you need to get from the source of the data), use lxy.proj.add.

• Argument proj4string which is an object of class CRS-class containing information about the new projection system. A good place to find the proj4 strings for a projection system is http://www.spatialreference.org.

Note that not all coordinate systems can be projected into all other coordinate systems. If you get an error message like 'non finite transformation detected', the coordinate system you are trying to project into may not be compatible with the existing coordinate system.
