Big Thank You! to all who helped: @LukeTierney4 for initial issue and an excellent hint at fixing it, @kevin_ushey and others for comments---but chiefly @Enchufa2 for picking up my branch and running (much) further with it. Now in #Rcpp 1.0.6.3 after another PR polish. #rstats
Many thanks to @Enchufa2 and the #Rstats people for solving this: github.com/RcppCore/Rcpp/iss… Very important fix for running millions of #COVID19 simulations in the #babsimhospital project. We ♥️#opensource!

This morning's new #rstats helper function: show all _compiled_ dependencies of a package (as Kurt, Uwe and I correctly suspected an Rcpp rev.dep. issue would go away under fresh builds).
Now in littler as new example 'compiledDeps.r'. Easy thanks to @rdatatable and `tools`.

How it started How it's going
I modified the intra-day SP500 tracker by @joshua_ulrich, the refactored code is in my `dang` package.
More changes to come incl a 24hr version for ES and alike (no free data though).

Periodic reminder that @marutterstat is doing us #rstats users on @ubuntu a huge favour.
Relying on @rdatatable and my #Rcpp-based `RcppAPT` package, we see that we now have well over five thousand CRAN packages as pre-made binaries which is fabulous. Big thanks to Michael!

That's what I do :)
Glad to hear you find it useful.
First time using @eddelbuettel's #rstats 📦 {anytime} and I might just use it _all the time_ 🙌github.com/eddelbuettel/anyt…

No much slicker as previously discussed on r-devel and shown again today by Bill Dunlap:
> deparse(quote(mtcars |> subset(cyl == 4) |> d => lm(mpg ~ disp, data = d)))
[1] "lm(mpg ~ disp, data = subset(mtcars, cyl == 4))"
>
"Look, ma, no side effects"

Upcoming native pipe for R will support a lambda-alike operator '=>' when data needs to be assigned:
mtcars |> subset(cyl == 4) |> d => lm(mpg ~ disp, data = d)
which is quite nice and avoids the backslash lambda-alike.
See @LukeTierney4 on r-devel just now. #rstats

CRAN is handling an impressive load, and I just wanted to say "Thank You!" for fully automated processing of a (bug-fix, due to change in another package) release of `RcppArmadillo`. Initially stuck in pretest, the rest is quick given the 802 reverse dependencies. #rstats

In Germany, this is flying around social media. America is both a source of horror and a laughingstock.
