In activPAL: Advanced Processing and Chart Generation from activPAL Events Files

Description

Reads in a csv file containing a list of events file locations and overlay file locations, generating and saving spiral and linear charts for each events file aligning the events file data with the corresponding overlay data. Where the overlay data is non-continuous data (such as sleeps diaries) the csv file should have the columns start_time (dd-mm-YYYY HH:MM), end_time (dd-mm-YYYY HH:MM) and category (text). Where the overlay data is continuous data (such as continuous glucose monitoring) the csv file should have the columns start_time (dd-mm-YYYY HH:MM) and category (text). In this case the end time coincides with the start time of the subsequent observation. The charts are saved as png images with two images generated for each events file / overlay file pair (one spiral chart and one linear chart).
Note: Spiral plots are generated using ggplot2 and coord_polar() and can take 45 - 60 seconds to generate each spiral plot.

Usage

activity.with.overlay.chart.folder(index_file_location, output_folder)

Arguments

index_file_location	The filepath for the csv file with the following column names file_id, events_file, overlay_file
output_folder	The filepath of the folder where the generated chart are to be saved to
