trackeR 1.6.1

Bug fixes

• Fixed a bug that would result inplot_route()returning empty output.

• RemovedgridExtra andgtablefrom imports in favour ofpatchwork.

Enhancements

• Documentation fixes.

trackeR 1.6.0

Bug fixes

• Fixed a bug that could result inreadTCX() populatingcadence_cycling with running cadence data.
• Guard againstdata.frame’s with no “file” attribute intrackeRdata().
• Fixed a bug that could cause no units to be shown in the labels onthe plots fromplot.distrProfile() andplot.conProfile().

Enhancements

• added support for “m_per_min” speed units (functionsm_per_min2X() andX2m_per_min() whereX are other speed units).
• Fixedplot_route() andleaflet_route() towork withggmap’s transition to Stadia maps.
• Various documentation updates.

trackeR 1.5.2

Bug fixes

• Power is now extracted correctly from.gpx files(thanks to Andrew from for spotting the issue).

Enhancements

• readX functions support reading from compressedversions (.gz,.bz2,.xz,.zip) of.tcx,.gpx,.json files.
• Example data files are now compressed and more is provided.
• Vignette and documentation updates.
• Provided example inread_directory().

trackeR 1.5.1

Bug fixes

• Fixed a bug that would result in errors fromget_elevation_gain() if altitude has too many NAs.
• smooth_elevation_gain is not passed correctly inread_directory().
• change_units.trackeRthresholds() is now exported.

New functionality

• get_elevation_gain now has thevertical_noise option to threshold absolute elevationgain.

trackeR 1.5.0

Bug fixes

• Fixed a bug inplot.trackeRdataSummary() wheretemperature and altitude would haveNULL label on theresulting plot.

New functionality

• Added support for cumulative elevation gain(trackeRdata andtrackeRdataSummary objectsand associated methods).

Enhancements

• readGPX() tries even harder to identify the sport.
• Documentation improvements.

trackeR 1.4.1

Bug fixes

• Fixed bug that would discard temperature and latitude whentrackeRdataSummary objects were fortified withmelt = TRUE.

trackeR 1.4.0

Bug fixes

• Fixed bug that could result in an error may appear when printingsummaries for non-thresholded objects.

trackeR 1.3.0

New functionality

• threshold.trackeRdata() reports on the progress of theoperation iftrace = TRUE in its arguments.

Enhancements

• Added new logo
• Updated documentation

Bug fixes

• Fixed a bug that causedthreshold to not threshold ifapplied without specifying any of variable, lower, upper and sport.

Other changes

• plot_route() now returns plots using stamen maps (see?ggmap::get_map() for the reasons we are moving away fromother maps).

trackeR 1.2.0

Other changes

Updated vignettes to avoid errors during CRAN checks

trackeR 1.1.0

New functionality

• Multi-sport support (cycling, running, swimming)
• Comprehensive support for temperature recordings from devices
• readGPX() for reading Strava GPX files
• readX functions now return objects with asport attribute with values (cycling,running,swimming)
• trackeRdata objects now have a print method with basicsummaries
• ridges() method fortrackeRdata,distrProfile andconProfile objects forridgeline plots of concentration profiles
• nsessions(),sport(),session_duration() andsession_times() methodsfortrackeRdata andtrackeRdataSummaryobjects
• auto_breaks argument when plotting zones, distributionand concentration profiles
• sort() andunique() methods fortrackeRdata objects

Enhancements

• Numerous under-the-hood performance and design improvements
• Refactored code forreadTCX(); reading Garmin TCX isnow notably faster (circa 15x faster) and more robust
• Refactored code forsummary() method fortrackeRdata objects, making it faster (circa 10xfaster)
• Code improvements inreadDirectory()
• c() improvements fortrackeRdataobjects
• readDirectory() can be performed in parallel usingforeach
• sane multi-platform parallelization across methods usingforeach. The parallel backend and its details needs to beset by the user
• Wprime has been adapted for a multisport environment
• Enhancements to the definition of thetrackeRdataobject and the associated methods; the object now carries file and sportinformation

Bug fixes

• Various bug fixes intrackeRdata
• Fixed bug inscaled() method that would cause an errorfor single sessions
• Theaggregate() method is now doing what is supposedto

Other changes

• Maintainer changed from Hannah Frick to Ioannis Kosmidis
• Robin Hornak joined developer team as author

trackeR 1.0.0

• Added citation for JSS paper.

trackeR 0.0.5

• The colour palette for plots of trackeRdataZones objects is now alsobased on black/blue.
• The vignette Tour de trackeR and the examples forplotRoute() now use maps from Stamen rather thanOpenStreetMap.

trackeR 0.0.4

• The sanity checks performed when creating a trackeRdata object nowthrow warnings. This can be switched off with the argumentsilent = TRUE.
• The colour palette for plots of trackeRdataSummary andtrackeRdataZones objects changed slightly.

trackeR 0.0.3

• plotRoute() can now include more than one session inone plot. The new functionleafletRoute() uses the leafletpackage to produce an interactive map.
• Added a method for distribution and concentration profiles to fit afunctional principal components analysis and a plot function toaccompany it.
• Added a second, shorter vignette “Tour de trackeR” to illustratebasic features and new functionality.
• Added a new timeline plot for trackeRdata object to visualise thedate time of the sessions.
• Added a new nsessions method to access the number of sessions invarious trackeR objects.
• Updated “runs” data object by splitting former session 20 into 2sessions as the two parts of the session took place in two differentplace with a break of over 1.5 hours between them.

trackeR 0.0.2

• The scale options has been removed from the distribution profile andis now set-up as a separate operation. In this implementation firstsmoothing and then scaling (the right order for those operations) ispossible.
• Some improvements for trackeRdata(): session containing noinformation beyond the timestamps are removed; conversions betweendistance and speed now recognise the respective units.
• Distribution profile: if all values of the variable for which theprofile is to be calculated are missing, the profile (and its smoothedversion) will also consist of only NA (rather than throwing anerror).
• Experimental support for reading Golden Cheetah’s JSON files.

trackeR 0.0.1

• First CRAN release of new “trackeR” package which providesinfrastructure for handling running and cycling data from GPS-enabledtracking devices. See vignette(“trackeR”, package = “trackeR”) fordetails.
