Preserving equations in Powerpoint when going cross-platform

This is another one of those tricks that I forget how to do unless I write it down. When I move Powerpoint (2010) presentations from my Windows machine to my Mac (Powerpoint 2011), the equations usually get destroyed along the way. The workaround is to turn the equations into images that can’t be altered by the Mac.

For example, here I’ve got an equation plopped into a blank presentation, with the equation editor toolbar.

The equation.

The equation.

The first step is to copy the entire equation and the text box … Continue Reading

Part 2: Make your R figures legible in Powerpoint/Keynote presentations

In the previous post, I outlined some tips for increasing the size of figure labels for figures that are meant to be displayed on a projector. The previous post used the base R plot() function, but the procedure when plotting with ggplot2 is different and usually quite a bit simpler than the stock R plotting functions. As before, I’m outputting the figures here as 1024×768 PNG image files, since they’re sure to work in whatever version of PowerPoint or Keynote you’re stuck using.

I’ll begin by generating some random data and dates to use in the plots. … Continue Reading

Make your R figures legible in Powerpoint/Keynote presentations

Having just returned from the SICB 2014 meetings, the appearance of many people’s Powerpoint figures is fresh on my mind. The sheer number of tiny figure labels (tick marks, axis titles, legend text etc) is disappointing. If we want to point fingers, MATLAB users are clearly the worst offenders because of the microscopic default label sizes in that program, but there are plenty of illegible R and matplotlib figures out there as well. Excel is obviously its own special class of terrible, but we will speak of it no more. The default settings in most of these programs … Continue Reading
