QR code, can be generated with R?

Question

Can QR codes be generated in R? Is there is a package that allows it?

You can now: https://github.com/hrbrmstr/qrencoder – hrbrmstr Aug 02 '15 at 19:38 — hrbrmstr, Aug 02 '15 at 19:38

Now on CRAN

You can use the qrencoder package - https://github.com/hrbrmstr/qrencoder - to do this. It begs the question: "Why?", though

par(mar=c(0,0,0,0))
image(qrencode_raster("http://rud.is/b"), 
      asp=1, col=c("white", "black"), axes=FALSE, 
      xlab="", ylab="")

*Why?* - I heard the digital currencies are the first practical usage of QR codes. See [accept payments in shiny app](http://www.r-bloggers.com/accept-payments-in-shiny-app/) – jangorecki Aug 05 '15 at 00:02

There's also a CRAN package called qrcode now. check this: https://cran.r-project.org/web/packages/qrcode/index.html

usage is a as simple as it gets:

library(qrcode)
qrcode_gen('www.r-project.org')
