New Post on combining #rstats with Fortran via #rcpp

Possible world audience of three:
@ProfJamesCurran (who asked initial question),
@jb_duckmayr@twitter.com
who answered (years earlier!!),
@AvrahamAdler@twitter.com
who is all in on Fortran. And me mediating :)

RcppTOML 0.2.2 on CRAN: Now with macOS-on-Intel Builds
Better configuration files for humans and machines
https://dirk.eddelbuettel.com/blog/2023/01/29#rcpptoml_0.2.2
#rcpp #rstats

Note that I propose an alternative non-parametric empirical Bayesian estimator here: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4269537 and present the code in #rstats and #rcpp

(Retooting Dariia's tweet over here)

#RStats 4.3.0 will default to C++17 (with the 'where available' caveat, just how it currently defaults to C++14). Lots of packages still specify C++11 explicitly and can just drop that (at least for builds under recent R versions). #rcpp #datascience

PSA: CRAN package `BH` is looking to update to version 1.81.0 of the recently-released Boost_Libraries 1.81.0 (with a large subset, as usual).

Reverse-depends checks show 300+ packages unaffected, and we track and PRed a handful others. See below for details and how to test your package with the release candidate.

@mpjdem @johannes_lehmann I also used Rcpp to write iteration steps in C++. Even my crap C++ code can be substantially faster than my best R code for heavy iteration processes. #rstats #Rcpp #cpp

Here is an example in this paper: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4269537

I replaced a step that I was doing with a combination of iteration and matrix manipulation, with two iteration steps in C++.

Hey, #rstats pkg devs, we are trying #cpp11, and it seems that #roxygen2 tags won't work like they do with #Rcpp. Is this a thing? cc @Emil_Hvitfeldt
