How unusual is it for TLDs to resolve to an address at the top most level? (a.k.a. a sneaky, basic introduction to dplyr)

I saw this on Hacker News this morning and it got me curious as to how many other TLDs (e.g. .com) resolve to an address (i.e. http://uz./ displays a page in your browser since uz. resolves to 91.212.89.8). This is quick work with R and the resolv & iptools packages, plus I threw in a little...

Adding CITATION to your R package

Original post from Robin's Blog:Software is very important in science – but good software takes time and effort that could be used to do other work instead. I believe that it is important to do this work – but to make it worthwhile, people need to get credit for their work, and in academia that...

It provides an option (not recommended) to auto-update any packages with newer development versions. The reason auto updating is...

Do your "data janitor work" like a boss with dplyr

Data “janitor-work” The New York Times recently ran a piece on wrangling and cleaning data: “For Big-Data Scientists, ‘Janitor Work’ Is Key Hurdle to Insights” Whether you call it “janitor-work,” wrangling/munging, cleaning/cleansing/scrubbing, tidying, or something else, the article above is worth a read (even though it implicitly denigrates the important work that your housekeeping staff does). It’s...
