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 https://abs.twimg.com/emoji/v2/... draggable="false" alt="🌟" title="Glowing star" aria-label="Emoji: Glowing star"> devs interacted with each other + to https://abs.twimg.com/emoji/v2/... draggable="false" alt="👀" title="Eyes" aria-label="Emoji: Eyes"> was considered improper

Setting">https://twitter.com/fellgerno... R 4.0.0 properly was painful due to https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤯" title="Exploding head" aria-label="Emoji: Exploding head">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">https://twitter.com/fellgerno...

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 https://abs.twimg.com/emoji/v2/... draggable="false" alt="⚠️" title="Warning sign" aria-label="Emoji: Warning sign">

Installing everything is easier now (no homebrew https://abs.twimg.com/emoji/v2/... draggable="false" alt="⚠️" title="Warning sign" aria-label="Emoji: Warning sign">). But it’s confusing when you google errors & the first answers give you (now) outdated info.

You’ll see that big https://abs.twimg.com/emoji/v2/... draggable="false" alt="🟥" title="Red square" aria-label="Emoji: Red square">!

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