cycleRdata: cycleRdata class

Description

A class for imported ride files intended to ease integration with package functionality. Produced by invoking read_ride (or equivalent) with the argument format = TRUE. Fundamentally, cycleRdata objects are a special type of data.frame; special in the sense that column names are predefined and assumed to be present in the class' associated methods. Modification of these column names will lead to errors. See below for a description of the format.

Usage

is.cycleRdata(x)
as.cycleRdata(x)

Arguments

an object to be tested/coerced.

Format

The columns of cycleRdata objects are structured as such:

timer.s: an ongoing timer (seconds). Stoppages are not recorded per se, but rather represented as breaks in the continuity of the timer.
timer.min: as above, but in units of minutes.
timestamp: "POSIXct" values, describing the actual time of day.
delta.t: delta time values (seconds).
lat: latitude values (degrees).
lng: longitude values (degrees).
distance.km: cumulative distance (kilometres).
speed.kmh: speed in kilometres per hour.
elevation.m: altitude in metres.
delta.elev: delta elevation (metres).
VAM: "vertical ascent metres per second".
power.W: power readings (Watts).
power.smooth.W: an exponentially-weighted 25-second moving average of power values.
work.kJ: cumulative work (kilojoules).
Wexp.kJ: W' expended in units of kilojoules. See ?Wbal and references therein.
cadence.rpm: pedalling cadence (revolutions per minute).
hr.bpm: Heart rate (beats per minute).
lap: a numeric vector of lap "levels". Will only have values > 1 if lap data is available.
