QR codes have been all the rage in the past few years. Below are my simple steps to quickly making a single QR code either online, using a design application (e.g. Canvas) or through R.
General steps
A straightforward way to generate a QR code is to pick one of the many online tools to do it. Here are a few I have used (note some of the links might be broken):
- One option here
- Another one here: This one is a little simpler
- I used this one: I liked this one because of easy custom image insert but im sure they are all “much of a muchness”
- Medium blog https://medium.com/@gliechtenstein/build-a-qrcode-barcode-scanning-app-with-26-lines-of-json-b83453d39197

An extention
I have used a simple design app made for data scientists and social media advertisers to make simple and quick designs. It is called desygner. This is not the only option and paint will do but this free (basics anyway) gets the image sizes closer than I know how with my mind and a “paint” brush.
And Another
This same tech is used for creating and catalogueing databases (even jekyll ones).
