move (version 1.0)

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:
    moveTo create an object containing one animal track moveStackTo create an object containing multiple move objects getMovebankDataTo create a Move or a MoveStack object with data from Movebank

II. Calculation of the utilization distribution

With the function below the dynamic Brownian Bridge Movement Model calculates the utilization density from a Move object: ll{ brownian.bridge.dyn To calculate the utilization density }

III. Accessing values

ll{ 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 time.lag 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: ll{ 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
