An overview of the functions in this package

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

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

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
