moveBB: Create a 'MoveBB' object

In moveBB: Analysis of Trajectory Data using Linear or Brownian Motion Model

Description

This method creates an object of type MoveBB or MoveBBStack.

Usage

## S4 method for signature 'ANY,ANY,missing,ANY,ANY,ANY'
moveBB(x,y,var,time,data,proj,...)
## S4 method for signature 'ANY,ANY,numeric,ANY,missing,ANY'
moveBB(x,y,var,time,data,proj,...)
## S4 method for signature 'numeric,numeric,numeric,POSIXct,data.frame,ANY'
moveBB(x,y,var,time,data,proj,sensor='unknown',animal='unnamed',...)

Arguments

x	vector of x coordinates(e.g. data$x)
y	vector of y coordinates
var	vector of location variances
time	column indicator for non-Movebank data for the time stamps, with POSIXct conversion, i.e. as.POSIXct(data$timestamp, format="%Y-%m-%d %H:%M:%S", tz="UTC")
data	Optional extra data associated with the relocations, if empty it is filled with the coordinates and timestamps
proj	projection method; requires a valid CRS (see CRS-class) object, like CRS("+proj=longlat +ellps=WGS84"); default is NA
sensor	sensor name, either single character or a vector with length of the number of coordinates
animal	animal ID or name, either single character or a vector with length of the number of coordinates
...	Additional arguments

Examples

	data(vervet_monkeys)
	
	head(monkey.data)
	
	## Generates an object of type MoveBBStack, where the individual trajectories
	## are identified by the value of the "GroupDayNo" field.
	tr <- moveBB(monkey.data$X, monkey.data$Y, monkey.data$StdDev^2,
	        monkey.data$DateTime, animal=monkey.data$GroupDayNo, 
	        data=monkey.data, proj="+proj=utm +zone=36 +south ellps=WGS84")
	
	split(tr) ## Get a list of MoveBB objects
