The ones that are not from CRAN were only included if they passed the check test ( R CMD check more details here ). The packages are mainly from CRAN and a few of them are from other repositories. The packages included here are mainly tracking packages though we include a subsection of other movement-related packages. We encourage the users to verify how coordinates are processed in the packages, as the consequences can be important in terms of spatial attributes (e.g. Regarding (x,y), some packages may assume 2-D Euclidean (Cartesian) coordinates, and others may assume geographic (longitude/latitude) coordinates. However, a package analyzing accelerometry series to detect changes in behavior would not fit. For instance, a package that would use accelerometer, gyroscope and magnetometer data to reconstruct an objects’s trajectory-most likely an animal’s trajectory-via dead-reckoning, thus transforming those data into an (x,y,t) format, would fit into the definition. The packages listed here, henceforth called tracking packages, are those explicitly developed to either create, transform or analyze tracking data (i.e. (x,y,t)), allowing a full workflow from raw data from tracking devices to final analytical outcome. ![]() Tracking data are composed by at least 2-dimensional spatial coordinates (x,y) and a time index (t), and can be seen as the geometric representation (the trajectory) of an object’s path. Movement of an object (both living organisms and inanimate objects) is defined as a change in its geographic location in time, so movement data can be defined by a space and a time component.

Besides the maintainers, the following people contributed to the creation of this task view: Achim Zeileis, Edzer Pebesma, Michael Sumner, Matthew E. This CRAN Task View (CTV) contains a list of packages useful for the processing and analysis of tracking data. See the CRAN Task View Initiative for more details. For example, ctv::install.views("Tracking", coreOnly = TRUE) installs all the core packages or ctv::update.views("Tracking") installs all packages that are not yet installed and up-to-date. The packages from this task view can be installed automatically using the ctv package. CRAN Task View: Processing and Analysis of Tracking Data. For further details see the Contributing guide. Suggestions and improvements for this task view are very welcome and can be made through issues or pull requests on GitHub or via e-mail to the maintainer address. We'd advise you to contact the package sender or your shipping carrier for clarification.CRAN Task View: Processing and Analysis of Tracking Data CRAN Task View: Processing and Analysis of Tracking Data Maintainer: Due to complex description of worldwide shipping providers, we can't auto-detect and determine all the status 100% accurately, hope you understand. However, if you haven't received your package and it is under the'Alert' status, then please pay attention: you need to read and analyze the detailed tracking information carefully. If you ensure your package has been delivered successfully, please ignore this notice. ![]() Your package may have suffered damage or been lost during the transportation period. ![]() ![]() Your package might be retained by customs department due to any of these reasons: contains prohibited goods importation of the goods is restricted retained by customs due to tax payable, or any other unspecified reasons.Your package is being returned to sender due to any of these reasons: item refused by addressee incorrect / illegible / incomplete address expired retention period addressee absence etc.Item might undergo unusual shipping condition, this may due to several reasons, most likely item was returned to sender, customs issue, lost, damaged etc.
