Then please don't look at my 170+ official @Debian packages 😉

I upgraded my "operating system" today! Emacs 27.1 with added vterm support is wicked! See the gif (maybe in a new tab) with htop, #byobu, #Rstats devel with pipe and lambda---all inside an Emacs vterm.
To try, use @Ubuntu 20.04 binaries from my PPA: launchpad.net/~edd/+archive/…

An even closer match may be his `SharedObject` package.

Thanks to @Rami_Krispin and his colleagues for having me talk #Rcpp (and #rstats) today.

It is almost blasphemy when @spotify runs an ad, and the application display only rewrites part of the previous song.
Because as @mcbridesworld would ascertain (thanks for that *awesome* Jazz Night in America playlist, btw), John Coltrane did not play "Daisy Sour Cream"....

Seconded -- @BrodieGaslam is a wizard and we had good luck combining `diffobj` with the wonderful `tinytest` package (by @markvdloo) in out `ttdo` package: unit testing with clean #rstats object diffs.
{diffobj} lib in #R @rstudio allow to compare objs (even complex) and view differences side-by-side:
diffobj::diffPrint(target=dataset, current=dataset2)
In pic1 the output (one value diff in row1)
In pic2 an example with two complex lists of tibble objs
very handy! #Rstats

That's very kind of you to test. The package _itself_ does little (other than squat on lots of sectors of your disk) but it is the _reverse dependencies_ that matter. So if you don't author a package against it, no worries. Thanks though.
Once again #rstats release candidate test help needed: #Boost 1.75.0 was released yesterday; I just made the (annual) update to BH 1.75.0-0.
So if you use BH, please test it via the #ghrr drat:
Rscript -e 'install.packages("BH", repos="ghrr.github.io/drat")'

"Interesting" study. @rdatatable is number 140 among the top 200 C language projects -- and I did not see any other pure #Rstats projects.
@XGBoostProject is 30th, #mlpack 44th, #lightgbm 84th, #spdlog 95th, @QuantLib 133rd among C++ projects.

Jiefei Wang from @RoswellPark gave the single best #ALTREP presentation (for #rstats internals) I have seen
yesterday at the @Bioconductor developer forum. The recording is available at the link below.

The #RockerProject provides two images updated each weekend:
rocker/drd -- a little smaller
rocker/r-devel -- initial one, larger
In both please use `RD` not `R` as they also contain r-release along with r-devel.
Happy piping!

RC test help needed: Eigen 3.3.9 came out yesterday; the @mcmc_stan #rstats folks nudged me to update (to 3.3.8, overdue). So if you use RcppEigen, please test it via the #Rcpp drat:
Rscript -e 'install.packages("RcppEigen", repos="rcppcore.github.io/drat")'
