Put a bird on it - Portlandia.
If you missed out on Portlandia, you should take some time to watch this clip of the “Put a bird on it” episode.
Just like Bryce and Lisa - we can put birds on anything with the magick package from ROpenSci!
So let’s get started putting birds on things!
The magick package is an R interface to the ImageMagick STL, one of the most comprehensive open source image processing libraries. It gives a lot of power to R users, and we’ll briefly cover the workflow before getting into our real example.
If you want a deeper dive on all the features of magick, check out their awesome vignette!

We can also view the image in line.
