Parse activity samples from a GT3X file

Parse activity samples from a GT3X file

parseGT3X(
  filename,
  max_samples,
  scale_factor,
  sample_rate,
  start_time,
  verbose = FALSE,
  debug = FALSE,
  impute_zeroes = FALSE
)

Arguments

filename	(char*) path to a log.bin file inside the unzipped gt3x folder, which contains the activity samples
max_samples	Maximum number of rows to parse. The returned matrix will always contain this number of rows, having zeroes if not data is found.
scale_factor	Scale factor for the activity samples.
sample_rate	sampling rate for activity samples.
start_time	starting time of the sample recording.
verbose	Print the parameters from the log.bin file and other messages?
debug	Print information for every activity second
impute_zeroes	Impute zeros in case there are missingness?

Value

Returns a matrix with max_samples rows and 3 columns with the acceleration samples. The matrix has attributes "time_index", "missingness", "start_time_log", "sample_rate", "impute_zeroes".
