Water, Fat and Protein content of meat samples
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.
