Description
Computes the specified order trigonometric moment for a set of directional data points.
Usage
1
trig.moment(x, p=1, center=FALSE)
Arguments
x
directional data set measured in radians.
p
order of trigonometric moment to be computed. Default is for a first order trigonometric moment.
center
logical flag whether to compute centered moments or not. Default is to compute an uncentered moment.
Value
Returns a data frame with variables mu.p, rho.p, cos.p, and sin.p, respectively the pth trigonometric moment's direction, resultant length, and real and imaginary components.
