1. Matrix - Methods and Classes - R package with S4 classes and methods for matrices, linking to state-of-the-art algorithms for dense and sparse matrices, notably Lapack, CHOLMOD and Csparse.
Development Status: 5 - Production/Stable [Filter]
2. Functional diversity - The "Functional diversity" project is based on the FD package, which can compute different multidimensional FD indices. It also contains other useful tools for functional ecology, e.g. trait-based community assembly via maximum entropy models.
Development Status: 5 - Production/Stable [Filter]
4. expm - Matrix exponential - Efficient calculation of the exponential of a matrix. The package contains an R interface and a C API that package authors can use.
