Francisco Requena (@datarequena; 10): @AlmuinaAlberto Try the function blogdown::check_site(). It can be useful to identify possible errors in your configuration

Tiffany Timbers (@TiffanyTimbers; 83): Do you have a word document template that you are required to use at work? Would you prefer to use R Markdown instead? You can do just that! > @xieyihui has kindly documented this here: and made a video as well:

Gordon Shotwell 🇨🇦 (@gshotwell; 71): @ryangarnett78 @hadleywickham @JennyBryan @sharlagelfand @rstudio Yup! Indeed it’s easy, all you need is to include a template in a package. >

Tianyu Li (@TianyuLiTTU; 41): Applied Missing Data Analysis with SPSS and Rstudio Book_MI.knit #rmarkdown #bookdown

numericalguy (@numericalguy; 31): A few pointers why my #bookdown would not make a PDF file of the book - long overall paths and names of files - \linebreak without having any text before it - having equations in headings #rmarkdown #rstudio

tj mahr 🍍🍕 (@tjmahr; 30): @grrrck I use a notebook system built on targets so that I can jot down things in separate Rmd files and put them together in a cleanrmd bookdown single html document. That’s my code bubble thing.

Tiffany Timbers (@TiffanyTimbers; 30): If you do this (create a Rmd for a specific word doc template), and want to be able to easily share with others you can go a step further, and make this an R package! >

Matt Kerlogue (@mattkerlogue; 30): @dtoher If the chunk is set to show the code then it will show the comments, as they are part of the code. But they can add comments outside the chunk using the html comment tag <!– your comment –>

Jordi Rosell (@jrosell; 21): @Leesplez Or if you really like Google Drive you can use rmdrive (I didn’t tried myself yet)

Alexandra Bagaïni (@a_bagaini; 21): @hadleywickham It is possible that they’ve read The Pirate’s Guide to #rstats by @YaRrrBook:

Kai! (@kaioinformatics; 10): @kierisi *bookdown/gitbook. I think people are also hesitant to say ‘this is who is important’, with the implication that anyone not listed is not important

David Kahle (@davidjkahle; 10): @Leesplez For academic journal templates, have you checked out the rticles package?

Lewis G (@LewisGeer; 10): Stumbled upon a concise and clear textbook on statistical computing by @rdpeng of JHU: So nice to find books like Fermi’s Thermodynamics that are stepwise with the motivation precisely stated at each step.

ذوزنقه (@soosanageh; 10): @MyMazinLife

Kamil Skowron (@kamilskowron; 10): @mkumm As far as I understand, Leanpub is limited in the case of fine-tuning how PDF is generated. As I started using bookdown, I applied multiple changes to the source of the book(to make it look better) so it drifted away from the markdown format/PDF output supported by Leanpub

Michi Tobler (@michitobler; 10): @SapCaps @KateLaskowski Never mind… yes it is. I think bookdown it is!

Dr. Serena Padilla-Caplins (@SapCaps; 10): @KateLaskowski @michitobler Yup Rmarkdown or Jupiter notebook depending on which language you’re interested in using. Rmarkdown can be used to generate html files and through bookdown and github can be made into a website.

Qing Zhang (@qingzzzzzz1; 10): A nice piece on nested regression

Tony Hirst (@psychemedia; 10): @Connor11528 @andreazonca Try jupyter book… or use jupytext to to convert to Rmd and use bookdown?

Yihui Xie (@xieyihui; 80): @JohnHelveston @StatStas That’s indeed a good exercise. It happens that I wrote knitr::combine_words() precisely because I was invited to teach a guest lecture to undergraduates in 2014.

Yihui Xie (@xieyihui; 70): @StatStas @jaredlander @JohnHelveston You don’t need a wrapper function—knitr::combine_words(oxford_comma = FALSE) removes the Oxford comma.

Remco (@Remco72348684; 60): @dtoher It’s possible. Adding eg. echo = 2 will only show line 2 of that chunk

CAA-SSLA (@CAA_SSLA; 40): @benmarwick Sooo, what packages are used by archaeologists? Per paper about 8.5 packages (median). The most often used packages are ggplot2, knitr, dplyr, devtools, raster and tidyverse. So most often mentioned are some for data manipulation, visualisation and the writing of paper.

tj mahr 🍍🍕 (@tjmahr; 20): @softnoumenon @gongcastro yes because of how knitr/rmarkdown can assume a different default working directory than the project root

Jose Barrera (@overdispersion; 11): @TiffanyTimbers I have never used WYSWYG because I learn LaTeX before I needed to write my first presentation. Always LaTeX (reports, presentations, posters, journal articles, …), with knitr if data analysis is involved 😊

DavidLawrenceMiller (@millerdl; 10): fun fact: I corrected these manually in my knitr/LyX doco, only to find that the code in the doco no longer works! ✅

Meghan Hall (@MeghanMHall; 30): During the event someone asked in chat if I could share the .Rmd file for the slides, as an example of a simple xaringan presentation, so I’ve linked the code there, as well.

Sevenap (@StoyMuTriste; 20): Tiene el xaringan el gaara

Alex Sanchez Pla (@sanplaale; 20): @TiffanyTimbers Of course they are! Who might think differently? I have banned PowerPoint and alike from my classes and students have very quickly become proficient in Xaringan, Beamer or whatever they have chosen to use.

Nithin .M (@nithin_eco; 10): @Prathkum But shadow not appearing in bullet items. Ofcourse not in html, but xaringan. Any idea?
