R package with statistical tests and methods for genetic association studies with emphasis on rare variants and binary (dichotomous) traits

R package with handy functions to help users select and play with color schemes in an HSV color model

Functions for Discriminant Analysis and Classification purposes covering various methods such as descriptive, geometric, linear, quadratic, PLS, as well as qualitative discriminant analyses

Implementation of the function 'arcplot' for plotting pretty arc diagrams ('arcdiagram' can be seen as a plugin for the 'igraph' package)

Implementation of simple functions to draw basic path diagrams just for visualization purposes.

pathmox, the cousin package of plspm, provides a very interesting solution for handling segmentation variables in PLS Path Modeling: segmentation trees in PLS Path Modeling.

plsdepot contains different methods for PLS analysis of one or two data tables such as Tucker's Inter-Battery, NIPALS, SIMPLS, SIMPLS-CA, PLS Regression, and PLS Canonical Analysis. The main reference for this software is the awesome book (in French) 'La Regression PLS: Theorie et Pratique' by Michel Tenenhaus.

Partial Least Squares Path Modeling (PLS-PM) analysis for both metric and non-metric data, as well as REBUS analysis.

Package designed for working with vectors and lists of vectors, mainly for turning them into other indexed data structures.

A collection of matrix functions for teaching and learning matrix linear algebra as used in multivariate statistical methods. These functions are mainly for tutorial purposes in learning matrix algebra ideas using R. In some cases, functions are provided for concepts available elsewhere in R, but where the function call or name is not obvious. In other cases, functions are provided to show or demonstrate an algorithm. In addition, a collection of functions are provided for drawing vector diagrams in 2D and 3D.
