The (native R) bioinformatician's urge to use @eddelbuettel's littler (dirk.eddelbuettel.com/code/l…) to programmatically calculate genome index sizes in a pipeline because the expression contains a log and I know the syntax in R and don't want to mess with figuring it out in NF/groovy

Markets and empirical science measurements need Nanosecond resolution
@eddelbuettel R #rstats nanotime handler:
github.com/eddelbuettel/nano…
Since Python 3.7 the time.time_ns() function returns nanoseconds as an integer since the epoch (but accuracy depends on OS & hardware)

Particularly fun project as it was my first serious time using Rcpp in a package and after some early teething, I'm so impressed how smooth it is to write and link C++ functions in R.

Thanks to the hard-working CRAN maintainers, brmsmargins is up cran.r-project.org/package=b…
it helps calculate population average predictions / marginal effects from (Bayesian) mixed effects models. Thanks to @eddelbuettel @mcmc_stan @paulbuerkner for the tools that made it possible

America's grim milestone of 800,000 covid-related deaths is an undercount according to @TheEconomist's excess-mortality model. Russia's official tally is likely to be much further from its true toll

No, and yes. John expressed this as "turning users into programmers". So both natural and normal.
And 40 years after "Interface", he wrote an entire book about it. In it, Principle III states "Interfaces to other software a part of R" #rstats

Well, by design, and called "Interface" a full fourty-five years ago (when using only Fortran).
See Chambers (2020) and his books for more (and e.g. references in my presentations) with the famous Bell Labs drawing of the "Interface". #rstats

Another STAT 447 is in the books, and a big thank you and congratulations to all students. Group projects were impressive (see below). Been thinking about "external" project topics for Data Science Programming Methods, may open a GH repo. Get in touch if interested. #rstats

Please please please tell your prof you liked the class. Please!!!!
Is it normal/okay to email a professor telling them you really enjoyed the class and learned a lot? I really enjoyed this course and would love to express my gratitude to my professor, but idk if that like weird or frowned up, you know? :(

PSA: If g++-11 produces errors like "reference to ‘data’ is ambiguous", ensure you do not (accidentally ?) flatted the `std` namespace and one of your containing `data`.
C++17 brings us `std::data()` which can clash.
Illustration and fixes in repo.
