uiucthemes v0.3.0 Released - Illinois-themed Metropolis HTML and Beamer Templates

The uiucthemes package is an organizational R package that provides unified brand templates based on the University of Illinois at Urbana-Champaign’s (UIUC) identity guidelines. In particular, the package houses different Beamer and HTML slide templates hooked into R Markdown. After almost a year of no updates, uiucthemes has been updated to contain two new Illinois-themed templates based on the metropolis theme. In addition, the project has moved over to the illinois-r organization on GitHub.

RcppEnsmallen v0.2.10.3.1 Released - Backwards compatibility and vignette example!

The RcppEnsmallen package brings to R a Header-Only C++ Mathematical Optimization Library for Armadillo. In particular, Ensmallen is a templated C++ mathematical optimization library (by the MLPACK team) that provides a simple set of abstractions for writing an objective function to optimize. After the massive update that was 2.10.0, the Ensmallen Development Team has provided a patch for better backward compatibility with the 1.y.z series. In addition, there are a few bug fixes that attempt to address edge cases.

RcppEnsmallen v0.1.16.0.1 Released - New LBestPSO Optimizer and Objective Value Control

The RcppEnsmallen package brings to R a Header-Only C++ Mathematical Optimization Library for Armadillo. In particular, Ensmallen is a templated C++ mathematical optimization library (by the MLPACK team) that provides a simple set of abstractions for writing an objective function to optimize. Well, CRAN was on vacation when the Ensmallen Development Team released this version. So, there was a slight delay in getting it listed on CRAN. Within the new version, there is a new optimizer LBestPSO that was in the works for awhile now (~February 2019).

searcher v0.0.4 Released - Search RStudio Community and Read about Search Patterns!

The searcher package (CRAN, GitHub) provides a search interface to look up terms on popular websites such as ‘Google’, ‘Bing’, ‘DuckDuckGo’, ‘Startpage’, ‘StackOverflow’, ‘RStudio Community’, ‘GitHub’, and ‘BitBucket’. Upon calling a search_*() function, a browser window will open with the search results for the query. Within this release, searcher gains the ability to search the RStudio Community, improved documentation, and a new vignette on search patterns. In addition, the search_ixquick() function was deprecated in favor of search_startpage() as the company behind the search engines consolidated to startpage.

rvw 0.6.0: First release

Editor's Note: This post has been cross-posted on Dirk Eddelbuettel's website and on the rvw R package's GitHub page. The post was originally written by Ivan Pavlov, who worked on the project during Google Summer of Code (GSOC) 2018. Release Notes Today Dirk Eddelbuettel, James Balamuta and Ivan Pavlov are happy to announce the first release of a reworked R interface to the Vowpal Wabbit machine learning system. Started as a GSoC 2018 project, the new rvw package was built to give R users easier access to a variety of efficient machine learning algorithms.
