%description
Methods for comparing different regression algorithms for describing the
temporal dynamics of secondary tree growth (xylem and phloem). Users can
compare the accuracy of the most common fitting methods usually used to
analyse xylem and phloem data, i.e., Gompertz function, Double Gompertz
function, General Additive Models (GAMs); and an algorithm newly
introduced to the field, i.e., Bayesian Regularised Neural Networks
(brnn). The core function of the package is XPSgrowth(), while the results
can be interpreted using implemented generic S3 methods, such as plot()
and summary().
