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

In github-js/acc: Exploring Accelerometer Data

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.

##
## A example to read counts data
##
## Not run: 
# For Vaha-Ypya et al.'s method
accData1 <- readRaw("C:/mydata.csv",type='mad')
# For Bai et al.'s method with known resting state intensities
accData2 <- readRaw("C:/mydata.csv",type='ai',resting=c(.15,.16,.17))
# Calculating resting state intensity for Bai et al.'s method
restingIntensity <- readRaw("C:/mydata.csv",type='resting')
accData3 <- readRaw("C:/mydata.csv",type='ai',resting=restingIntensity)

## End(Not run)
