With extrafont, you can use Computer Modern in a PDF figure without using TikZ. Some R users use TikZ (with the tikzDevice package) to create figures that use Computer Modern, to match the appearance of the document text. If you are creating a document with TeX, there's a good chance that your document uses the default font, Computer Modern. Using Computer Modern (with math symbols) That way, there will be a single copy of the font in the document instead of one for each figure. If you have many PDF figures that are being put into a single PDF document, it can be more space-efficient to embed the fonts in the final document, instead of in each figure. To embed the fonts, use embed_fonts(): # If you don't specify 'outfile', it will overwrite the original fileĮmbed_fonts("plot_garamond.pdf", outfile="plot_garamond_embed.pdf")Įmbed_fonts("ggplot_garamond.pdf", outfile="ggplot_garamond_embed.pdf") Sys.setenv(R_GSCMD = "C:/Program Files/gs/gs9.05/bin/gswin32c.exe") # Adjust the path to match your installation of Ghostscript If you're using Windows, you'll also need to tell R where the Ghostscript executable is: # For Windows - in each session You'll need to make sure it's installed on your computer (note that GhostScript is not an R package).

This must be run once in each R session where you want to use the fonts: library(extrafont) Once you've imported the fonts from your system to the extrafont database, they must be registered with R as being available for the PDF output device. # This will show more detailed information about fonts

After the fonts are imported, you can view the available fonts by running fonts() or fonttable(): fonts() You may see some warnings, but you should be able to ignore them.

The first step is to install extrafont, and then import the fonts from your system into the extrafont database: Installation install.packages("extrafont") It will substitute some other font in the place of Garamond: Here's an example of what a PDF using Garamond might look like when it's not embedded, and printed or viewed on a device that lacks the font. Next, you must embed the font into the PDF file to make it render properly on another computer or printer that doesn't already have the font. When using fonts in PDF files, there are two challenges: First you must tell R that the font is available to use. With it, you can create beautiful, professional-looking results like this: Using other fonts that are installed on your computer can seem an impossible task, especially if you want to save the output to PDF.įortunately, the extrafont package makes this process much easier. When it comes to making figures in R, you can use any font you like, as long as it's Helvetica, Times, or Courier.
