Scatter Correction Spectra plots with R

These are the spectra of an Infratec 1241 for Soy meal treated with "Multiple Scatter Correction", "Standard Normal Variate" and "Standard Normal Variate  + Detrend", apart from the "Raw Spectra".

All this math treatments are in the new Video Series (in spanish) from the posts last weeks.

In next post we see the effect of derivatives in the spectra, and we continue with Principal Components and Regressions Methods.
