Details

There is an option hrbrthemes.loadfonts which -- if set to TRUE -- will call extrafont::loadfonts() to register non-core fonts with R PDF & PostScript devices. If you are running under Windows, the package calls the same function to register non-core fonts with the Windows graphics device.

Why Roboto Condensed?

It's free, has tolerable kerning pairs and multiple weights. It's also different than Arial Narrow and the fonts most folks use in ggplot2 charts.
