create_test_acc_csv

Sample frequency in Hertz, the default here is low to minimize file size

Number of minutes (minimum is 2000)

Nmin

Location where the test file named testfile.csv will be stored
 If no value is provided then the function uses the current 
 working directory

storagelocation

Creates file in the Actigraph csv data format with dummy data
that can be used for testing. The file includes accelerometer data 
with bouts of higher acceleration, variations non-movement periods
in a range of accelerometer positions to allow for testing the
auto-calibration functionality.

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://www.activinsights.com/> and GENEA devices (not for sale), .csv-export data from 'Actigraph' <https://actigraphcorp.com> devices, and .cwa and .wav-format 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 and has either no header or a two column header. Also the package allows for external function embedding.
