%description
Parallel computing, multi-core CPU is used to efficiently compute and
process multi-dimensional soil data.This package includes the parallelized
Quantile Regression Forests algorithm for Digital Soil Mapping and is
mainly dependent on the package 'quantregForest' and 'snowfall'. Detailed
references to the R package and the web site are described in the methods,
as detailed in the method documentation.
