The format is:
..$absorp.fdata: absorbance data. fdata class object with:
"data": Matrix of class fdata with 215 curves (rows) discretized in 100 points or argvals (columns).
"argvals": 100 discretization points from 850 to 1050mm
"rangeval"=(850,1050): range("argvals")
"names" list with: main an overall title "Tecator data set", xlab title for x axis "Wavelength (mm)" and ylab title for y axis "Absorbances".
..$y: the percentages of Fat, Water and Protein. The three contents are determined by analytic chemistry.
Details
absorp.fdata absorbance data for 215 samples. The first 129 were originally used as a training set
