satRday Cape Town
SA’s first R conference – Almost a full month has passed since satRday Cape Town. Time races on (as always) bringing plenty of challenges and opportunities with each new day, but part of me wants to go back and re-live the experience, just to have some more time to take it all in again. It’s an event which I hope will remain f...

R track on exercism.io

The spark of statistics
The science of us – I’ve enjoyed maths for pretty much as long as I can remember. I’m aware that it is rare to make such a statement. Probably straight up weird to some. But that just shows how much I have to be grateful for. I am indebted to my parents, extended family and friends and a number of great teachers over the ye...

Naming things is hard
Prefixing R function names – ‘There are only two hard things in Computer Science: cache invalidation and naming things.’ The above quip by Phil Karlton is fairly well known and often quoted, sometimes with amusing extensions: There are two hard things in computer science: cache invalidation, naming things, and off-by-one error...
