lxy.merge: Merges LoCoH-xy object

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

Description

Merges LoCoH-xy objects together

Usage

lxy.merge(..., pts.flds = "all", save.ptid = FALSE, new.id = NULL,
  save.old.id = NULL, dt.int.round.to = 0.1, tau.diff.max = 0.02)

Arguments

...	LoCoH-xy objects
pts.flds	A character vector of column names to include in the merged object, can also be "all" or NULL
save.ptid	If duplicate ptid values are encounted in the merged object, whether to save the original ptid values as an ancillary variable, T/F
new.id	A new id value for the merged object
save.old.id	A boolean or the name of a ancillary variable where the old id values will be saved
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 (the median delta.t of the entire dataset), expressed as a proportion of tau, that time difference between two points must fall for the distance between those two points to be included in the calculation of the median step length

Details

The coordinate system of the LoCoH-xy objects being merged must be the same. Also each lxy object must have the same data columns present, e.g., dt, col, ancillary variables, etc. To merge a subset of the attribute fields, use the pts.flds parameter.

Because LoCoH-xy object must have unique ptid values for each location, if the merged object contains duplicate ptid values new one will be created. If save.ptid=TRUE, the 'old' ptid values will be saved as ptid.orig.

The merged object will no have nearest neighbors table and the random walk parameters will be recomputed.
