Recommended: Convert PowerPoint Slides to xaringan (remark.js) Slides

I have been constructing most of my recent presentations to R Markdown. This includes presentations that have little or no R code in them. I like using R Markdown because you are manipulating simple text files. This makes it easy to use version control, among other things.

There’s a new package, which I have not tried yet, that will do a direct translation of a PowerPoint file into R Markdown. It uses a presentation format (xaringan) that I personally do not like, but it should be pretty easy to switch from xaringan to a different format like ioslides. The package owner warns that you will probably have to tweak the resulting R Markdown code to get it perfect, but the package should do “get you about 90% of the way there for about 80% of use cases.” That’s still a huge time savings.

PMean: Equations using MathType

I’m ordinarily not a big fan of commercial software, but one product that I would have a hard time living without is MathType. It produces mathematical equations with ease and the appearance is almost always perfect. It’s hard to do this, especially with equations have lots of superscripts and subscripts. You get the size or spacing wrong and all of a sudden things look really ugly and it is hard to fix. TeX is a very good product, too, but I have grown so used to MathType that it is really hard to make the switch.  I had to upgrade MathType recently to version 6.9 and I wanted to experiment with MathType equations on my blog. Here are some examples. Continue reading
