5. 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]
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.
11. 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.
