GGIR-package | A package to process multi-day raw accelerometer data
data.calibrate | Example output from g.calibrate
data.getmeta | Example output from g.getmeta
data.inspectfile | Example output from g.inspectfile
g.analyse | function to analsyse meta-data generated by g.getmeta and g.impute
g.binread | function to read binary files as produced by the accelerometer named 'Genea', not to be confused with the 'GENEActiv' (see package GENEAread for this)
g.calibrate | function to estimate calibration error and make recommendation for addressing it
g.getbout | function to calculate bouts from vector of binary classes
g.getmeta | function to extract meta-data (features) from data in accelerometer file
g.impute | function to identify invalid periods in the meta-data as generated by g.getmeta and to impute these invalid periods with the average of similar timepoints on other days of the measurement
g.inspectfile | function to inspect accelerometer file for brand, sample frequency and header
g.part1 | function to load and pre-process acceleration files
g.part2 | function to analyse and summarize pre-processed output from g.part1
g.part3 | Detection of sustained inactivity periods as needed for sleep detection in g.part4.
g.part4 | Labels detected sustained inactivity periods by g.part3 as either nocturnal sleep or daytime sustained inactivity
g.part5 | Merge output from physical activity and sleep analysis into one report
g.plot | function to generate a plot for quality check purposes
g.shell.GGIR | Shell function for analysing an accelerometer dataset.
