Easy Loading and Installing of Packages (easypackages)
Easily load and install multiple packages from different sources, including CRAN and GitHub. The libraries function allows you to load or attach multiple packages in the same function call. The packages function will load one or more packages, and install any packages that are not installed on your system (after prompting you). Also included is a from_import function that allows you to import specific functions from a package into the global environment.
Using Keel in R Code (RKEEL)
KEEL is a popular Java software for a large number of different knowledge data discovery tasks. This package takes the advantages of KEEL and R, allowing to use KEEL algorithms in simple R code. The implemented R code layer between R and KEEL makes easy both using KEEL algorithms in R as implementing new algorithms for ‘RKEEL’ in a very simple way. It includes more than 100 algorithms for classification, regression and preprocess, which allows a more complete experimentation process. For more information about KEEL, see <http://…/>.
Manipulation of Linear Systems of (in)Equalities (lintools)
Variable elimination (Gaussian elimination, Fourier-Motzkin elimination), Moore-Penrose pseudoinverse, reduction to reduced row echelon form, value substitution, projecting a vector on the convex polytope described by a system of (in)equations, removing spurious columns and rows and collapse implied equalities.
