Adding strings in R

October 5, 2018 | Jonathan Carroll

This started out as a “hey, I wonder…” sort of thing, but as usual, they tend to end up as interesting voyages into the deepest depths of code, so I thought I’d write it up and share. Shoutout to [@coolbutuseless](https://twitter.com/coolbutuseless) for proving that a little ...

JC and the Vignettes

March 6, 2018 | Jonathan Carroll

If that’s not a great 1960’s band name then I don’t know what is (hint: I don’t know what is). At the start of the year I set out my ‘goals for 2018’ just like many of us do; an overly ambitious list of things we’d like ...

Thou shalt not compare numeric values (except when it works)

September 4, 2017 | Jonathan Carroll

This was just going to be a few Tweets but it ended up being a bit of a rollercoaster of learning for me, and I haven’t blogged in far too long, so I’m writing it up quickly as a ‘hey look at that’ example for newcomers. I’ve ...

Data Munging With R Preview — Storing Values (Assigning)

June 26, 2017 | Jonathan Carroll

Since about October last year, I’ve been writing an introduction to R book. It’s been quite the experience. I’ve finally started making time to document some of the interesting things I’ve learned (about R, about writing, about how to bring...Continue Reading →

Here in the land down under we've finally completed our Federal election. We complain that it seems to go on for too long, but it's a brief distraction compared to the USA electoral process. I managed to do a small...Continue Reading →

Images as x-axis labels (updated)

June 2, 2016 | Jonathan Carroll

They say "if you want to find an answer on the internet, just present a wrong one as fact. Then wait." It didn't take long, actually. Despite my searches while trying to get images into x-axis labels it seems I...Continue Reading →

Images as x-axis labels

June 2, 2016 | Jonathan Carroll

Open-source software is awesome. If I found that a piece of closed-source software was missing a feature that I wanted, well, bad luck. I probably couldn’t even tell if was actually missing or if I just didn’t know about it....Continue Reading → [Read more...]
