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.

[Read More]52vis Week 2 Challenge -- Australian Version
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.
[Read More]Bring on the ROpenSci #auunconf 2016!
I’ll be heading to the 2016 ROpenSci un-conference (hackathon) in Brisbane later this month to smash out a heap of open-science R code. Ideas are already flowing quite nicely, and I’m confident that any ideas we don’t end up officially working on will get their chance in the very near future.
