load_tcx_file: Process a single tcx file

In VCCRI/CardiacProfileR: Generate Heart Rate Dynamic Profiles from TCX Data

Description

process a single tcx file and return and energies dataframe.

Usage

load_tcx_file(filename)

Arguments

filename

A filepath to a tcx file (.tcx)

Value

The energies dataframe from the file at filename energy dataframe :

• totalE : total energy expenditure

• deltaE : delta energy expenditure

• bpm : heart rate in beats per minute (bpm)

• deltaBPM: delta heart rate in beats per minute (bpm)

• time : POSIXct timestamps

• rawbpm : raw unsmoothed heart rate
