Hello 👋

I’m Nicola Rennie, a data scientist at Jumping Rivers, R enthusiast, data visualisation lover, among other things. My personal website is hosted at

This website contains for documentation for the R packages I’ve created. I have developed R packages for generative art, data analysis, data visualisation; and outlier detection. The documentation for all of my publicly available R packages can be found on
