# knitr

> **John MacKintosh** (@_johnmackintosh; 9/2): Today I  learned (or relearned) about knitr::cache() in order to refer to a variable in a rmarkdown document before it's been created.
> So here I'm picking up the latest Specimen Date, (and formatting it ) even though, at time of knitting / rendering, the data isn't loaded. https://t.co/0NYaK0msas  [&#8618;](https://twitter.com/_johnmackintosh/status/1432814448771665923)

> **Andrew Heiss, geriatric millennial** (@andrewheiss; 4/1): Update to this! You can now pass additional arguments to dvisvgm with knitr's engine.opts chunk option, so embedding fonts in TikZ-based SVG images from knitr is super easy now! See update in action here: https://t.co/fAus46h4Wb #rstats https://t.co/rOD4LJx9xS  [&#8618;](https://twitter.com/andrewheiss/status/1432358158786195463)

> **John MacKintosh** (@_johnmackintosh; 4/1): The latest specimen date is `r format(knitr::load_cache('setup1','maxdate'), '%d %B, %Y')` "

> setup1 = name of chunk where variable is created
> maxdate = name of variable

> **Andrew Heiss, geriatric millennial** (@andrewheiss; 2/1): One more update to this—it's possible to change fonts in tikz knitr chunks so that you're not stuck with Computer Modern! It just takes a little bit of LaTeX trickery.

> **Will Ball** (@WillBall12; 2/0): @_johnmackintosh 'You have to let knitr know if the data file has been changed. One way to do it is to add another chunk option cache.extra = file.mtime('my-precious.csv') or more rigorously, cache.extra = tools::md5sum('my-precious.csv').'

> **Mine Çetinkaya-Rundel** (@minebocek; 101/20): Yesterday I realized that you can embed @Slidoapp polls in #rstats xaringan slides, they even provide the iframe embed code. Along with @grrrck's xaringanExtra panes and countdown timer, it's pretty straightforward to add some interactivity to slides. https://t.co/FOt7Q2ZSAE  [&#8618;](https://twitter.com/minebocek/status/1433470213119520777)

> **Kato Online** (@KatoOnline; 3/0): @grrrck Hi Garrick, is it possible to tell XaringanExtra::use_webcam() which device to use? I have a few devices and can't figure out how to get xaringan to use the camera device I prefer for it. Is that possible?  [&#8618;](https://twitter.com/KatoOnline/status/1432335708048531457)

<!-- -->


> **Blas M. Benito** (@BlasBenito; 1/0): @thi_sanna The effort needed to do exactly what you want is on par with what my dear old Beamer requires, so I cannot see any advantages of xaringan so far, unless the slides focus heavily on code rather than ideas.
