move-package: An overview of the functions in this package

Description

move is a package that contains functions to access movement data stored at www.movebank.org as well as tools to visualize and statistically analyse animal movement data. Move addresses movement ecological questions.

Arguments

I. Creating Move objects

Move objects can be created from files with the function:

II. Calculation of the utilization distribution

With the function below the dynamic Brownian Bridge Movement Model calculates the utilization density from a Move object:

brownian.bridge.dyn

To calculate the utilization density

III. Accessing values

coordinates

Track-coordinates of the Move Object

as.data.frame

A data.frame with the important data of the Move Object

n.locs

The number of locations

timeLag

The time lags between the locations

projection

The projection method of the track/raster

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

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
