move-package {move}R Documentation

An overview of the functions in this package

Description

move is a package that contains functions to access movement data stored on Movebank as well as tools to visualize and statistically analyse animal movement data. Move addresses ecological questions regarding movement.

Details

The package implements classes for movement data and supports

I. Creating Move objects

Move objects can be created from files with the function:

move To create an object containing one animal track
moveStack To create an object containing multiple move objects
getMovebankData To create a Move or a MoveStack object with data from Movebank

II. Calculation of the utilization distribution

The dynamic Brownian Bridge Movement Model calculates the occurrences distribution of a given track

brownian.bridge.dyn To calculate the occurrences distribution
getVolumeUD To calculate the Utilization distribution (UD)

III. Accessing values

bbox Bounding box of a Move* object
coordinates Track-coordinates of a Move* object
extent Extent of a Move* object
namesIndiv Names of a Move* object
n.locs The number of locations a Move* object
projection The projection method of a Move* object or raster
timeLag The time lags between the locations of a Move* object
timestamps Track-timestamps of a Move* object

IV. Plotting data

The track or the utilization distribution can be plotted with the following functions:

plot plots the utilization distribution with fixed width and height ratio (see DBBMM-class), or the track (see Move-class)
image plots the utilization distribution fitted to the window
contour adds the contours of utilization distribution to a plot
