Infrastructure for Running, Cycling and Swimming Data from GPS-Enabled Tracking Devices R package trackeR version 1.6.1 CRAN Task View: SpatioTemporal (https://CRAN.R-project.org/view=SpatioTemporal) CRAN Task View: SportsAnalytics (https://CRAN.R-project.org/view=SportsAnalytics) CRAN Task View: Tracking (https://CRAN.R-project.org/view=Tracking) Provides infrastructure for handling running, cycling and swimming data from GPS-enabled tracking devices within R. The package provides methods to extract, clean and organise workout and competition data into session-based and unit-aware data objects of class 'trackeRdata' (S3 class). The information can then be visualised, summarised, and analysed through flexible and extensible methods. Frick and Kosmidis (2017) <doi: 10.18637/jss.v082.i07>, which is updated and maintained as one of the vignettes, provides detailed descriptions of the package and its methods, and real-data demonstrations of the package functionality.
