Sure. I argue it has. Also Note that e.g. just yesterday the RConsortium cited the other package as a bright example of high quality (implicitly due to the funding they offered it). Yet a trifecta of a) fewer feature, b) equal or worse performance, c) few no users may say otherwise.

These factors may not apply for RcppArmadillo (a project I help with depends on it), but it's a good policy to have in general: If you can pass the CRAN check, follow the rules, etc. then you should get on CRAN. The "market" will decided.

Hey! Save the date as my new presentation for fantastic 🇺🇦Workshops for Ukraine 🇺🇦 by @dariia.bsky.social is coming up on Sep 25! And it's about:

💙 Intro to C++ programming for R applications for Econometricians 💛

Nice! ❤️🇺🇦

#IsupportUkraine #UKR #rstats #econometrics #Rcpp #RcppArmadillo #econsky
Intro to C++ programming for R applications for Econometricians Date: Thursday, September 25th, 18:00 - 20:00 CEST (Rome, Berlin, Paris timezone) Speaker: Tomasz Woniak is a Bayesian econometrician developing new econometric methods for applied macroeconomic research. He has been a specialised R user for seventeen years, and has recently joined The R Journal as an Associate Editor. He is the author of several R packages, available at https://bsvars.org/, that combine blazingly fast algorithms written in C++ with the convenience of data analysis in R. He works as a senior lecturer at the University of Melbourne, where he has an extensive research, teaching, and engagement portfolio. He is also an external collaborator at the International Labour Organization, where he develops a new forecasting system and an R package.

🖤 bsvars.org design concept pt. 3 💜

⭐ We use RcppArmadillo for linear algebra because we found it very fast on matrix operations and RNGs, well-documented, easy to use in packages. We 🖤 it! Seriously!

🌐 bsvars.org

#bsvars.org #bsvars #bsvarSIGNs #Rcpp #RcppArmadillo #rstats
bsvars.org design concept: Our packages use ReppArmadillo for linear algebra frontier package for linear algebra linking R with C++ library Armadillo; implements fast random number generators; makes C++ code as expressive as R's (or MATLAB's). we love it!
