computeVolume

Compute the Volume of a Specified Shift Range in a 2D Spectrum

This function takes a range of frequencies for each dimension, and calculates the volume of the enclosed region.

computeVolume(spectra, F2range = NULL, F1range = NULL)

`spectra`	An object of S3 class `Spectra2D`.
`F2range`	A formula giving a frequency range. May include "low" or "high" representing the extremes of the spectra. Values below or above the range of F2 are tolerated without notice and are handled as `min` or `max`, respectively.
`F1range`	As for `F2range`, but for the F1 dimension.

A numeric vector of volumes, one for each spectrum.
