Dynamic interaction refers to spatial-temporal associations in the movements of two (or more) animals. This package provides tools for calculating a suite of indices used for quantifying dynamic interaction with wildlife telemetry data. For more information on each of the methods employed see the references within. The package (as of version 0.3) also has new tools for automating contact analysis in large tracking datasets. The package draws heavily on the classes and methods developed in the 'adehabitat' packages.
*April 12, 2019 - This is a bunch of new functions to go along with a new paper under preparation - Added whole suite of contact analysis functions - Added GetTO function - Added new functionality to Prox, to allow for one-way mapping of proximity analysis - Added Benhamou Significance test to DI function - Added local analysis to IAB and DI functions
*Dec. 14, 2014 - Added three new functions to the package. - The IAB interaction statistic from Benhamou et al. (2014). - checkTO, a function which identifies if and when two telemetry datasets overlap (temporally). - contacts function, used to map point locations of contacts from telemetry data.
Aug. 14, 2014 - Changed package name from ditools to wildlifeDI for uploading to CRAN.
May. 19, 2014 - Fixed some issues in the documentation, changed default set-up of Lixn statistic.
Mar. 12, 2014 - Added new datasets: deer37 and deer38. Containing GPS fixes for a one week interval in March 2005 for two individual deer.
Oct. 24, 2013 - Fixed an error in GetSimultaneous influencing symmetry with irregular trajectories.
Feb. 11, 2013 - Fixed an error in calculation of Shirabe, if you are using this metric please re-run your analyses.
