April 30, 2017
By

Welcome to the sixth post in the really random R riffs series, or R4 for short. Posts #1 and #2 discussed how to get the now de rigeur package registration information computed. In essence, we pointed to something which R 3.4.0 would have, and provided tricks for accessing it while R 3.3.3 was still R-released. But now...

RcppTOML 0.1.3

April 24, 2017
By

A new bug fix release of RcppTOML arrived on CRAN today. Table arrays were (wrongly) not allowing for nesting; a simply recursion fix addresses this. RcppTOML brings TOML to R. TOML is a file format that is most suitable for configurations, as it is meant to be edited by humans but read by computers. It...

RcppQuantuccia 0.0.1

April 19, 2017
By

New package! And, as it happens, a effectively a subset or variant of one my oldest packages, RQuantLib. Fairly recently, Peter Caspers started to put together a header-only subset of QuantLib. He called this Quantuccia, and, upon me asking, said that it stands for "little sister" of QuantLib. Very nice. One design goal is to keep...

#5: Easy package information

April 14, 2017
By

Welcome to the fifth post in the recklessly rambling R rants series, or R4 for short. The third post showed an easy way to follow R development by monitoring (curated) changes on the NEWS file for the development version r-devel. As a concrete example, I mentioned that it has shown a nice new function (tools::CRAN_package_db()) coming up...

#4: Simpler shoulders()

Welcome to the fourth post in the repulsively random R ramblings series, or R4 for short. My twitter feed was buzzing about a nice (and as yet unpublished, ie not-on-CRAN) package https://github.com/dirkschumacher/thankr by Dirk Schumacher which compiles a a list of packages (ordered by maintainer count) for your current session (or installation or ...) with a...

#3: Follow R-devel

Welcome to the third post in the rarely relevant R recommendation series, or R4 for short. Today will be brief, but of some importance. In order to know where R is going next, few places provide a better vantage point than the actual ongoing developm...
