g.part5_initialise_ts

Initialise time series dataframe ts, part of g.part5.

internal

A tool to process and analyse data collected with wearable
raw acceleration sensors as described in Migueles and colleagues (JMPB
2019), and van Hees and colleagues (JApplPhysiol 2014; PLoSONE 2015).
The package has been developed and tested for binary data from
'GENEActiv' <https://activinsights.com/>, binary (.gt3x) and
.csv-export data from 'Actigraph' <https://ametris.com/> devices, and
binary (.cwa) and .csv-export data from 'Axivity'
<https://axivity.com>. These devices are currently widely used in
research on human daily physical activity. Further, the package can
handle accelerometer data file from any other sensor brand providing
that the data is stored in csv format. Also the package allows for
external function embedding.
