Using R and Shiny to create “Art”

One big strength of packages like shiny is the ability to easily vary parameters and view the results, especially in plots.

So here’s a small shiny app that I created to learn about reactivity, while also having fun.



The idea is simple. Vary many aspects of geom_segments in ggplot, and see what emerges. The things that I played with are canvas size, line origin and destination, line length, the angle and the colors.

Because it is art, I made the background black.

There were many experiments that didn’t appeal to me aesthetically. Others seemed very repetitive. The ones that seemed okay, I kept.

Take a look at the shiny app ShinySketch.
