Command

Make sure file_type is set to ‘mhealth’ and file_path is put in a vector.

Compute MIMS-unit values

# test on a sample file shipped with the package
sample_filepath = system.file("extdata", 'mhealth.csv', package='MIMSunit')
mims = MIMSunit::mims_unit_from_files(c(sample_filepath),
                                      epoch = '5 sec',
                                      dynamic_range = c(-2, 2),

Command

Make sure file_type is set to ‘mhealth’ and file_paths are sorted in time.
