You could try my course, it often gets PhD students from neighbouring departments. The course slides are up (and the videos are for Illinois students) and there are additional resources per topic on the course site: stat447.com

Reposting as 'live monitoring' of markets remains a timely topic given the recent changes---and the corresponding update of #RStats package `RcppRedis` is now on CRAN. And of course #notowarwithukraine

Which has the added advantage of already working today with the released version of #RStats 😀

Nice indeed. But then lm(mpg ~ disp, data = mtcars, subset = cyl==4) is still shorter, and quite possibly more readable. 😉 #rstats

Yo-Yo Ma, along with Emanuel Ax and Leonidas Kavakos, begins his performance at Washington’s Kennedy Center with a performance of Ukraine’s national anthem. A full, standing house.

It's a different context (i.e. our focus is within R), but we had something to day about the resulting complexity: tinyverse.org/ Simpler can be better / is often better. But for just about everything, tradeoffs exists, and need to be managed.

If you want to learn about #Rcpp for C++ and #Rstats integration, I will be giving a one-hour introduction on March 25 thanks to a kind invitation by @NISS_DataSci via Kevin Lee. Registration should be opening soon, more details at the link below. niss.org/events/rcpp-r-and-c…

Rcpp (R and C++) with Dirk Eddelbuettel

Overview R has risen to become the _lingua franca_ of statistical research and applications. At the same time, user demands on computing resources and performance have also increased. This is driven...

Suggestions: - wrap if (interactive()) around the call - randomly sample from statsquotes::statquote(), fortunes::fortune() and dang::demotiveate() to spice up your #rstats use

A man in Moscow buys a newspaper, glances at the front page, & throws it away. He does the same thing every day. Eventually, the seller snaps. "Why DO you do that?" "I'm just checking for an obituary" "But obituaries aren't on the front page!" "The one I'm looking for will be."

A few of us put this together last year: ess-intro.github.io/ Emacs is not for everyone, but it served me well for 25+ years with; ESS is amazing, I often keep many sessions persistently (daemon mode !) for weeks at a time. And then you have Magit and other goodies.

#RStats suggestion to sneak into your code: if (any(grepl("ru_RU",Sys.getlocale()))){ par(bg="#ffd700",mar=rep(0,4),xpd = NA) plot(0:1,0:1,type="n",xaxs="i",yaxs="i") rect(0,0.5,1,1,col="#0057b7", border=NA) }

Yep. It tends to become muscle memory, or you learn when you try to commit and the repo is behind :) BTW the higher-end variant is to edit the PS1 variable for your shell to show `git status`. There are a number of tutorials out there that should help given your shell.
