lopierra (@lopierra; 74): New post on my #blogdown site: trying patchwork, ggtext, and ggalt 📦📦📦 #rstats

Nami Sunami | 角南直幸 (@n_sunami; 62): Just sharing my first post on my website. It’s about the interests in video games and COVID-19 lockdown measures in the US. This is also an exercise for me to use RMarkdown, blogdown, and hugo.

Joshua de la Bruere (@delaBJL; 51): @toeb18 You’ve probably come across it already but the by @xieyihui @ProQuesAsker, and @apreshill is fantastic.

ouR Coding Club! (@ouRcodeclub; 42): Today at ouR coding club we talked rMarkdown, ggplot2, blogdown and more! But the more the merrier - join us next time on Nov 2nd @ 2:30 PM ET!

☠️ Duygu Uygun-Tunc ☠️ (@uygun_tunc; 40): @matherion I previously hesitated about R fearing that it’d take a lot of time given that I am a noob (I used to know C++ a bit in the past but that’s all gone now)–I’ll go for GitLab & the blogdown package! Thnx a lot, also @dsquintana and @tuncaburak

Silvia Canelón (@spcanelon; 30): @delaBJL @toeb18 @xieyihui @ProQuesAsker @apreshill +1 for the above! @apreshill is my go-to blogdown resource. Here are some materials/posts put together for a blogdown workshop series: And specific to Hugo, I found her Spoonful of Hugo blog posts to be very helpful:

Ischi_Mathes (@GregorMathes; 30): You can now look at my cv at my homepage and download it as a pdf file: > The whole website was built using the blogdown package, and the cv using the datadrivencv package. Or as one of my professors told me back then: “R is magic!” I should have listened.

Joshua de la Bruere (@delaBJL; 20): @toeb18 @xieyihui @ProQuesAsker @apreshill Yihui isn’t on twitter often but response to Github/Stack overflow questions quickly. Amber is doing fantastic work @puddingviz with data and web design Alison Also is phenomenal when it comes to blogdown.

Gjalt-Jorn Peters (@matherion; 20): @uygun_tunc I use Hugo with the Academic theme and then host on GitLab pages. That’s all Open Source, and with the blogdown package, quite easy to set up. You’re free to steal/clone one or more of my sites to hit the ground running, check my repos at or ask 🙂

Carlo Cavicchia (@carlocavicchia; 20): @signormirko I used by et al. for mine. It is simple and supports Hugo, Jekyll and Hexo. (Probably you are more expert than me but I found it very intuitive)

Mario Schädel (@mcranium92; 10): @GregorMathes Looks awesome! Do you have the code somewhere (GitHub etc.)? I did my website with Github pages and Jekyll (Ruby), but at some point I forgot how exactly I did it. So, I am thinking about rebuilding it with blogdown and proper documentation for my future self.

Alex Albright (@AllbriteAllday; 10): A few years ago, I built a #blogdown site for a student group I’m part of – I host it with Netlify and it deploys from a Github repo of mine. I now want to transfer management of the site. Opinions on best way to do this? @apreshill @ProQuesAsker @xieyihui

Erich Neuwirth (@neuwirthe; 10): @walterra Ich hab, während ich das Projekt gebaut habe, erst blogdown wirklich gelernt und würde es heute anders aufsetzen.

Dr. Straight but in a spooky mask for a while (@RyanStraight; 0/1): But now the preview looks good but when I knit and build the #blogdown site, my #Xaringan slide decks are just single, no-style HTML pages. 😣 Sigh. #rstats

Dana Wand-zer 🪄🎃 (@danawanzer; 213): This was probably not the smartest thing to do mid-semester, but it will also save me a lot of time as I transition my handouts from Word & SPSS to #bookdown & @jamovistats. Major thanks to @djnavarro (learn stats w/jamovi) and @LisaDeBruine (PsyTeachR) for CC & open materials!

Vebash (@Sciencificity; 154): In RMarkdown you sometimes have code that produces an error, but you want to include it in the rendered output. Add: error = TRUE in the code chunk header. The document knits without stopping at the error, since it is expected (R4DS learning). #rstats >

Martin Skarzynski (@marskar; 90): @ASpittel Your blog post is great, but the part about using three backticks instead of two can be a bit confusing. If you want to show a markdown code block in markdown, you can wrap the code block in 4 backticks:

- hello

Ben Balas (@bjbalas; 30): @ceptional Nice! I didn’t know about bookdown - will have to check this out. The nutshell version is that I’m aiming for something btw textbook and workbook. The emphasis is on observation and learning quantitative models for early/mid-level vision.

Alex Holcombe (@ceptional; 30): @bjbalas That’s cool, didn’t know/remember you were writing one! Interested in details! I used bookdown to write a little mini-text for one of my classes. It works well, I think; planning on using bookdown also for the #OA version of a book chapter.

talking bullocks, or an unblemished red heifer? (@thatbleepystuff; 10): @AlexBNewhouse Interesting. Bookdown looks great. Any thoughts on introducing it for documentation into projects / teams that otherwise have never used R, though? Is there anything else you’d recommend for such a use case? > I find that e.g. Github Flavoured Markdown lacks a lot of features.

Bryan Shalloway (@brshallo; 43): Messy approach to setting-up flags to interrupt rendering of #rstats Rmarkdown documents to allow for interactive inputs: (for those manually run, not-so-reproducible rmarkdown::render()ed reports where you don’t want to use params for some reason.)

KimEng Ky (@kykimeng; 32): knitr::purl() is probably the most underrated #rstats function ever!

Ethan Tenison (He, Él) 🏳️‍🌈 (@ethantenison; 10): @mrworthington @thomas_mock @jcheng I don’t think it’s possible. If it’s a really big project, you might consider using LATEX, which Knitr also accepts. The online LATEX editor Overleaf is pretty easy to use. After you set it up there you can download it and knit it for Shiny.

magdalena bennett (@maibennett; 51): @kierisi plotly, xaringan, and plotly again.

Mine Çetinkaya-Rundel (@minebocek; 40): @dgkeyes @yjunechoe Right, you either turn it off explicitly in xaringan, or with dev xaringan it’s off by default

June Choe (@yjunechoe; 40): Important update for anyone who made {xaringan} slides in the ~1-2 week period this month when these weird anchors were added in!

David Keyes (@dgkeyes; 40): @minebocek Ah, I see. It looks like this is new in the rmarkdown package so I need to set it so that xaringan doesn’t use this anchoring behavior. Thanks to you and @yjunechoe both!

Priyanga Dilini Talagala (@pridiltal; 40): @statsgen Thank you very much xaringan ninja 🥷👩‍💻

Gonzalo Martínez (@Gonzalupus; 32): El sabadaba dimos una plática sobre etnobotánica y algunos métodos usados en esta disciplina. Y pus para aprovechar me eché una presentación en #RStats con #xaringan y #xaringanExtra.

June Choe (@yjunechoe; 10): @dgkeyes I thought it was a weird new reveal.js dependency that made its way into xaringan but it does seem like it could be some broader knitting-to-html thing in rmarkdown(?) Would be interested to know if/where other folks are encountering this issue..

Dr. Straight but in a spooky mask for a while (@RyanStraight; 0/2): This is weird: when I’m previewing via infinite moon reader, my #Xaringan slides work just fine.
