decdc

This function is used to reduce the sampling rate of a time series by an integer factor.

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).

decdc function

<dl><dt>x</dt>
<dd>A data structure, vector or matrix containing the signal(s) to be decimated. If x is a matrix, each column is decimated separately.</dd>
<dt>df</dt>
<dd>The decimation factor. The output sampling rate is the input sampling rate divided by df. df must be an integer greater than 1.</dd>
<dt>go_slow</dt>
<dd>if TRUE the function will NOT use Rcpp to speed up convolution. Default is FALSE. This input is for testing and benchmarking.</dd></dl>
