We are the developers of several open-source packages, including the following:
XLConnect is one of the most widely used open source R packages for manipulating Excel files. XLConnect differs from other related R packages in that it is completely cross-platform and as such runs under Windows, Unix/Linux and Mac (32- and 64-bit).
rTRNG provides efficient, parallel, reproducible, and fair pseudo-random number generation for large-scale Monte Carlo simulations. The rTRNG package is based on the TRNG C++ library and provides a user-friendly R interface to it via Rcpp and RcppParallel packages.
compareWith is an R package providing user-friendly RStudio addins that make it easier to perform diff and merge tasks, especially with projects under version control. The package relies on Meld, a common visual diff and merge tool.
