Calculates the center of mass of a (simulated) school in 1D, 2D or 3D, or based on acoustic data.

Description

Calculates the center of mass of a (simulated) school in 1D, 2D or 3D, or based on acoustic data.

Usage

cm.school(school, mass = 1, subset = NULL, na.rm = TRUE, excl.neg = TRUE)

Arguments

school	is either a list of x-, y- and z-positions and mass of the fish (named "psxf", "psyf", "pszf" and "mass"), a list of x-, y- and z-positions and volume and acoustic intensity of the voxels (named "psxx", "psyx", "pszx", "volx" and "vbsc" or "mvbs"), or a matrix of columns holding the positions along each dimension.
mass	is the mass of the fish.
subset	is a numeric or logical vector defineing which positions to include in the calculation of center of mass.
na.rm	is used in sum().
excl.neg	is FALSE if negarive mass values are to be included in the calculation of the centers of mass of the school.
