If you want to use R Markdown to prepare research papers and presentations, you need to learn how to cite references and include a bibliography. This is a nice introduction and shows the variety of options at your fingertips. Continue reading

# Recommended: LaTeX/Mathematics

You can incorporate very nice looking mathematical formulas in R Markdown fairly easily. The system relies on LaTeX for displaying formulas and is surprisingly easy to learn. But every once in a while you want to do something a bit exotic, like placing a “hat” in your equation. I’ve typically just done a quick Google search on something like “LaTeX hat symbol” and each different search yields a different website. Recently, I stumbled up a fairly comprehensive guide to displaying mathematical formulas in LaTex. It is published as an eBook.

Note: Some of the examples require additional libraries like amsmath and I haven’t figured out yet how to take advantage of these libraries in R Markdown. Continue reading

# 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.

# Recommended: Make PowerPoint Presentations with R Markdown

This is a 42 minute presentation that covers the basics of using R Markdown to produce PowerPoint files. It touches on another couple of RStudio products: R Studio Connect and Shiny. This covers a lot of customizations issues. Also see Rendering PowerPoint Presentations with RStudio. Continue reading

# PMean: Small group presentations using screen sharing tools

I received a suggestion for the Kansas City R Users Group to use screen sharing tools. I am going to experiment with this a bit. Here are two tools worth trying. Continue reading

# PMean: Changing the font size in RStudio

Suppose you’re giving a talk and using R Studio. You want to make the fonts a bit larger so your audience can read them. It’s easy to do, once you know where to look. Continue reading

# PMean: Changing the font size in R

This is one of those obvious things that’s not obvious when you need it most. Suppose I’m doing a demo of R for a group like our wonderful Kansas City R Users Group. I want to have a readable sized font. Here’s how you do it. Continue reading

# 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

# Recommended: Data doesn’t speak for itself

This blog post explains that you can’t just put a graph up on a screen and immediately expect people to understand it. You need to provide critical context to help your audience. Continue reading
