readRaw: Reads raw data in .csv format for GT3X devices

Description

Reads raw data in .csv format for Actigraph GT3X devices. Device type and epoch is automatically detected and reported in the console. Marks activity intensity based on two existing methods.

Usage

readRaw(filepath,type,resting)

Arguments

filepath

Speficy full file path and file name. (e.g. 'C:/mydata.csv')

type

Specify how activity intensity is identified. Options: i) 'mad' for Vaha-Ypya method, ii) 'ai' for Bai et al.'s method, or iii) 'resting' to calculate resting state intensity level required for Bai's method

resting

Resting state intensity level, required for Bai et al.'s method.

Value

If the option 'type' is 'mad' or 'ai', five columns are returned, consisting of first four columns [TimeStamp,x,y,z], and the intensity category/level. If the option 'type' is 'resting' then a vector of resting state intensity level is returned.
