dtts 0.1.0 on CRAN: New Package
data.table time series ops at nanosecond resolution
dirk.eddelbuettel.com/blog/2…
#rstats #rcpp
Think `xts` but at nanosecond resolution. All the immense power of `data.table` at the hightest time resolution.

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:

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
R^4 Post #036: pub/sub with Redis and R
Real-time financial market monitoring with R and Redis

#rstats #rcpp
With lovely new code for pub/sub with @Redisinc, two examples for pub/sub for (financial) market monitoring, and two new vignettes.

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

It's a different context (i.e. our focus is within R), but we had something to day about the resulting complexity:

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.

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

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.

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.

So a really *big and heartfelt* Thank You! to everybody who helped along: the Rcpp Core team, all other contributors, and of course all users keeping us at it! #rstats
A *really big moment* for #Rcpp:
