get_samples_from_strata

a matrix of one column with the response variable.

original_order

sampling to select the calibration samples ("calibration")
or sampling to select the validation samples ("validation").

sampling_for

logical indicating if sampling with replacement must be
done.

replacement

starta

for internal use only! This function selects samples
based on provided strata.

Functions for dissimilarity analysis and memory-based learning
(MBL, a.k.a local modeling) in complex spectral data sets.
Most of these functions are based on the methods presented in
Ramirez-Lopez et al. (2013) <doi:10.1016/j.geoderma.2012.12.014>.
