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.
Dec. 10, 2012 - Formally added the Prox functionality to the toolset - added use of ld(), dl() everywhere to facilitate trajects with bursts
