Sum of Sines

Function to calculate a time series based on the sum of an arbitrary number of sine functions with different wavelengths, phases, and amplitudes.

sin.sum(t,wave=c(24, 24, 24*7, 24*7*365),
        phase=c(rep(0,length(wave))),
        amp=c(0,rep(1,length(wave))))

`t`	vector of increasing times at which to calculate the model
`wave`	vector containing the wavelengths of the sin functions
`phase`	vector containing the initial phases for the sin functions
`amp`	vector containing the initial amplitudes for the sin functions

Designed to be used with fit.ts.sin

Returns a vector with length equal to length(t) that consists of the sum of sine waves for each given time
