Interesting story behind recent issues, pull requests and updates for #Rcpp by @eddelbuettel

I read most of the recent issues & PRs to see how things unfolded. More for the social aspect to see how these 🌟 devs interacted with each other + to 👀 was considered improper

#rstats https://twitter.com/eddelbuettel/status/1248425917535289346
I was using Rcpp from GitHub as shown on the logs in https://twitter.com/fellgernon/status/1248261694197043201?s=21

Setting R 4.0.0 properly was painful due to 🤯docs/answers

Thx to pointers by Simon Urbanek I now have the proper macOS 10.15.4 R 4.0.0 alpha installation setup & can install pkgs from source if needed https://twitter.com/fellgernon/status/1247920656806805508
Now I see R 4.0.0 binaries available in CRAN and Bioconductor @Bioconductor (thx Hervé Pages!)

Simon (the expert!) recommends using clang from macOS & NOT using ~/.R/Makevars which is not what most blogs/answers say as this is a big change in R 4.0.0 ⚠️

Installing everything is easier now (no homebrew ⚠️). But it’s confusing when you google errors & the first answers give you (now) outdated info.

+ Simon pointed out how I was reading the wrong manual too 🤦🏽‍♂️

So 👀👉🏽 http://mac.r-project.org/  & (for now) https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#macOS âś…
You’ll see that big 🟥!

Removing flags means removing ~/.R/Makevars as I understand it

Diff/old advice https://github.com/rdatatable/data.table/wiki/installation#openmp-enabled-compiler-for-mac http://zhiyzuo.github.io/installation-rJava/ + many posts & community Q/A sites
