deliveryData

Approximately 15 days of 3-axis accelerometer data collected with 1-minute epoch.

datasets

It provides a function "wearingMarking" for classification of monitor
wear and nonwear time intervals in accelerometer data collected to assess
physical activity. The package also contains functions for making plot for
accelerometer data and obtaining the summary of various information including
daily monitor wear time and the mean monitor wear time during valid days.
"deliveryPred" and "markDelivery" can classify days for ActiGraph delivery by mail;
"deliveryPreprocess" can process accelerometry data for analysis by zeropadding incomplete
days and removing low activity days; "markPAI" can categorize physical activity
intensity level based on user-defined cut-points of accelerometer counts. It also
supports importing ActiGraph AGD files with "readActigraph" and "queryActigraph" functions.
