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 those two together) along the way.

They say “if you want to find an answer on the internet, just present a wrong one as fact. Then wait.”

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. When the source is available, maintained, and documented however, things get fun. We can identify, and perhaps fill gaps.

[Read More]Solving Inequality (the math kind)
This neat approach showed up recently as an answer to a FiveThirtyEight puzzle and of course I couldn’t help but throw it at dplyr as soon as I could. Turns out that’s not a terrible idea. The question posed is
optimise
200a + 100b + 50c + 25d
under the constraints
400a + 400b + 150c + 50d ≤ 1000, b ≤ a, a ≤ 1, c ≤ 8, d ≤ 4,

#auunconf slack users' timezone locations
I had never used slack before, but had read a heap of tech articles extolling its virtues. Apparently this is what our current Prime Minister advocates within Cabinet. The upcoming #auunconf organising team set up a channel and invited the participants, so I checked it out. Slack is pretty awesome as far as a unified workspace/messaging protocol can go. What makes it even more awesome, is that someone (@hrbrmstr, no surprise) has made an R package that talks to it.

I mapped out the USA homelessness rate in my last post as a challenge and noted at the end that it would be interesting to do the same for Australia. That was the first comment I received in person, too. “Let’s do it!” I said. What I found may shock you (click-bait title; check).

From Bob Rudis’ blog comes a weekly data/coding challenge. I didn’t quite get the time to tackle last week’s but I thought this one offered up a pretty good opportunity.
