QR codes in R

I was searching for a good, simple, and affordable QR code generator. It also had to be fast, as I needed to generate codes ad hoc during presentations and lectures.

I tested numerous options.

Eventually, it occurred to me to explore how to do it in R. After all, I write a blog in R, build a website in R (using blogdown), and create scripts for my classes in R (using bookdown).

And voilà! Of course, there’s the qrcode package (installation: install.packages("qrcode")).

With just one line of code:

plot(qrcode::qr_code("Hello world"))
