carbon, pH and clay content values. This data set has been collected by
oz dataset is the first 5 samples of
australia, and is here to keep examples fast to run.
data.frame contains the following columns:
sr_noa unique identifier for each spectrum
carbonsoil organic carbon values
phsoil pH values
claysoil clay values
X350, X351, ...,X2499, X2500reflectance in wavelengths 350 to 2500nm
Data kindly contributed by Raphael Viscarra Rossel. To reduce the size of the package, the original dataset has been reduced to 100 spectra using the Kennard-Stone algorithm.
