move (version 4.2.5)

move-package: 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.

Arguments

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.dynTo calculate the occurrences distribution
getVolumeUDTo calculate the Utilization distribution (UD)

III. Accessing values

bboxBounding box of a Move* object
coordinatesTrack-coordinates of a Move* object
extentExtent of a Move* object
namesIndivNames of a Move* object
n.locsThe number of locations a Move* object
projectionThe projection method of a Move* object or raster
timeLagThe time lags between the locations of a Move* object
timestampsTrack-timestamps of a Move* object

IV. Plotting data

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

plotplots the utilization distribution with fixed width and height ratio (see DBBMM-class), or the track (see Move-class)
imageplots the utilization distribution fitted to the window
contouradds the contours of utilization distribution to a plot

Details

The package implements classes for movement data and supports

  • Creation of Move objects (see Move-class) representing animals and their track

  • Calculation of utilization distributions using the dynamic Brownian bridge Movement Model

  • Plotting tracks, utilization distributions and contours

  • Access to raster, n.col, projection and coordinates

  • Different CRS projection methods such as longlat or aeqd
