hilbert_transform

This function is used to compute the Hilbert transform of a signal. It is based on function HilbertTransform() from (defunct) package hht, which was modified from the EMD package by Donghoh Kim and Hee-Seok Oh (http://dasan.sejong.ac.kr/~dhkim/software.emd.html)

High-resolution movement-sensor tags typically include accelerometers
to measure body posture and sudden movements or changes in speed,
magnetometers to measure direction of travel, and pressure sensors
to measure dive depth in aquatic or marine animals. The sensors in these tags usually sample many times per second. Some tags include sensors for speed, turning rate (gyroscopes), and sound. This package provides software tools to facilitate calibration, processing, and analysis of such data. Tools are provided for: data import/export;
calibration (from raw data to calibrated data in scientific units);
visualization (for example, multi-panel time-series plots);
data processing (such as event detection, calculation of derived metrics like jerk and
dynamic acceleration, dive detection, and dive parameter calculation); and statistical analysis (for example, track reconstruction, a rotation test, and Mahalanobis distance analysis).
