Extracts heart rate variability data from FIT files by analyzing RR intervals during both laying and standing positions. Implements robust filtering to maintain data quality and properly handle phase transitions.
Usage
extract_rr_data(
fit_object,
filter_factor = 0.15,
laying_time = 180,
standing_time = 180,
transition_buffer = 20
)Arguments
- fit_object
FITfileR object containing the FIT file data
- filter_factor
Numeric value (0-1) for filtering outliers. Higher values allow more variation between successive intervals
- laying_time
Duration in seconds for laying position (default: 180)
- standing_time
Duration in seconds for standing position (default: 180)
- transition_buffer
Time in seconds to exclude around position change (default: 5)
