activPAL (version 0.1.4)

activity.summary.by.window.duration: Summarise activity data from a folder of activPAL events files into equal sized periods

Description

activity.summary.window processes all the events files (format *Events.csv) in a folder and produces a summary table giving a breakdown of the number and duration of each event type across consecutive periods of a specified duration during the day. If the window_size is not a factor of 24, the final period will be shorter than the other reporting periods, generating a warning to advise of this difference in reporting period duration. The generated summary activity table for each events file is saved to a csv file, while an additional csv file containing the summaries across all the processed events files is also saved.

Usage

activity.summary.by.window.duration(input_folder, output_folder,
  window_duration = 2)

Arguments

input_folder

The filepath for the folder where the events files (format *Events.csv) to be processed are saved

output_folder

The filepath for the folder where the csv summary files are to be saved

window_duration

The size of each bucket in hours that the data is to be summarised. Default - 2 hours.

Examples

input_folder <- paste(system.file("extdata", "", package = "activPAL"),"/",sep="")
output_folder <- paste(tempdir(),"/",sep="")

activPAL::activity.summary.by.window.duration(input_folder,output_folder,2)

# Omitting a value for window_duration sets the default window size to 2 hours
activPAL::activity.summary.by.window.duration(input_folder,output_folder)

# You can set the window_duration to a time period that is not evenly divisible
# by 24 hours.  In this case the last reporting period for each day will be
# shorter than the specified window_duration.
