Eigenvalues and Singular Values and Vectors from Large Matrices (PRIMME)
R interface to PRIMME, a C library for computing a few eigenvalues and their corresponding eigenvectors of a real symmetric or complex Hermitian matrix. It can also compute singular values and vectors of a square or rectangular matrix. It can find largest, smallest, or interior singular/eigenvalues and can use preconditioning to accelerate convergence.

Information Matrix Test for Generalized Partial Credit Models (IMTest)
Implementation of the information matrix test for generalized partial credit models.

Unix System Utilities (unix)
Bindings to system utilities found in most Unix systems, mainly POSIX functions which are not part of the Standard C Library.

Inferring Condition-Specific Networks via Differential Network Inference (dc3net)
Performs differential network analysis to infer disease specific gene networks.

Helper Functions for Regression Analysis (reghelper)
A set of functions used to automate commonly used methods in regression analysis. This includes plotting interactions, calculating simple slopes, calculating standardized coefficients, etc. See the reghelper documentation for more information, documentation, and examples.
