summary.trackeRdata: Summary of training sessions

In trackeR: Infrastructure for Running, Cycling and Swimming Data from GPS-Enabled Tracking Devices

Description

Summary of training sessions

Usage

## S3 method for class 'trackeRdata'
summary(object, session = NULL,
  moving_threshold = NULL, unit_reference_sport = NULL, ...)

Arguments

object	An object of class trackeRdata.
session	A numeric vector of the sessions to be summarised, defaults to all sessions.
moving_threshold	A named vector of 3 speeds above which an athlete is considered moving, given in the unit of the speed measurements in object. If NULL (default), the speeds are taken to be c(cycling = 2, running = 1, swimming = 0.5). See Details.
unit_reference_sport	The sport to inherit units from (default is taken to be the most frequent sport in object).
...	Currently not used.

Details

The default speed thresholds are 1 m/s for running (3.6 km/h; slow walking), 2 m/s for cycling (7.2 km/h) for cycling and 0.5 m/s (1.8km/h) for swimming. For reference, the preferred walking speed for humans is around 1.4 m/s (Bohannon, 1997).

The units for the computed summaries match those of the sport specified by unit_reference_sport.

If object has thresholds then the thresholds that match those of the sport specified by unit_reference_sport are applied to the respective summaries.

Value

An object of class trackeRdataSummary.
