Dear colegues,

Is there any function in R for calculating the four coefficients of each
harmonic in fourier analysis, from a set of x,y coordinates is given? Is it
possible to do Fourier analysis?
Has anyone done contour analysis using R?

Any help wil be apretiated,

Thank you very much,
All the best,
