comment spectrum and phase of function in frequency domain
Got it guys. Once I have the fourier transform computed analytically, I can easily set up the complex vector and compute the amplitude and phase. R has support for complex numbers ugrad.stat.ubc.ca/R/library/base/html/complex.html and includes functions for finding amplitude and phase. Thanks all.

Sweet. Do you happen to come across function in R that does this similar to matlab?
