australia: Australia spectra library data set

In pierreroudier/inspectr: Storing, Manipulating and Analysis Spectroscopy and Associated Data in R

Description

The australia data set gathers 100 soil spectra, along side with their organic carbon, pH and clay content values. This data set has been collected by CSIRO.The oz dataset is the first 5 samples of australia, and is here to keep examples fast to run.

The 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
