This is an example of what is commonly known as "functional data analysis," or "fda" for short. You can search on this term to learn more. R has an fda package that deals with this sort of data -- and very likely others besides: essentially you have a 200-d response vector and so require a multivar

[R] repeatability/intraclass with nested levels

I have a spectrophotometric dataset with repeated measures of a value at 200 wavelengths for each of 150 individuals. I would like to use the repeated samples to at each wavelength to look at measurement/observer error, compared to difference between individuals error I have looked at doing
