0. The Soil Texture Wizard- The Soil Texture Wizard is a set of R functions designed to produce texture triangle plots. It also allows to classify soil textures data according to a classification, and to transform them according to different texture particle size class systems.
Development Status : 5 - Production/Stable [Filter]
8. Generalized ridge trace plots- The genridge package introduces generalizations of the standard univariate ridge trace plot used in ridge regression and related methods. These graphical methods show both bias and precision.
9. Plot manageable subsets of data- Plotting a large data set is difficult if it does not fit into memory as a data frame, so we introduce more efficient data structures and alternative plot functions that work with large data.
