Matt Johnson 🏵️ (@mrjoh3; 31): @MilesMcBain @coolbutuseless The viewer panel and integration with knitr, shiny, package documentation, test and build tools leave me not feeling the need to explore alternatives. Oh, and Rstudio addins are really handy and easy to build to simplify any workflow

Omar Wasow (@owasow; 30): @TomPepinsky @benlauderdale @rudeboybert @old_man_chester Also, a focus on speed or elegance of syntax misses that much of statistical work is communication not computation. Magical publishing tools like knitr, rmarkdown & Xaringan (thx @xieyihui!) and other major extensions like ggplot are huge advantages of R vs Julia & Python.

Courtney Hilton (@courtneybhilton; 30): @Sakiera_Hudson No problem. Also, run a summary() on it at the end for a more interpretable output and if you’re working with a .rmd (it only works on .R) you can convert it to a .R file first with knitr::purl()

Francisco Garre (@Fran_gfr; 20): @patilindrajeets I have read that to highlight functions in R markdown output you have to change the highlighting options before using knitr. Here is where I read it (I hope it helps). >

Have you tried the dev version of reticulate ?

Karina Bartolomé 💚 (@karbartolome; 10): @CitocromoB1 Hola! Va así directo como puse, sin argumento, al incluir un chunk con el código knitr::knit_exit(), luego de knittear el documento se renderiza hasta el lugar en donde incluiste ese chunk

Max Kuhn (@topepos; 10): @TiffanyTimbers @juliasilge One thing we need to do better is to wrap or truncate messages coming from base R or other packages (e.g. “rank deficient matrices”).

Danielle Navarro (@djnavarro; 20): @maryclarecc If you’re looking to create a short résumé in this style using {pagedown}, the nice thing is that the default template will recreate this resume from R markdown: > > If that looks close enough to what you’re hoping for, it might be fairly straightforward?
