JC and the Vignettes

If that’s not a great 1960’s band name then I don’t know what is (hint: I don’t know what is).

Data Munging With R Preview - Storing Values (Assigning)

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, [Read More]

#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.
