Counting [U.S.] Expatriation with R (a.k.a. a Decade of Desertion)

If you’re even remotely following the super insane U.S. 2016 POTUS circus election you’ve no doubt seen a resurgence of “if X gets elected, I’m moving to Y” claims by folks who are “anti” one candidate or another. The Washington Examiner did a story on last quarter’s U.S. expatriation numbers. I didn’t realize we had... Continue reading...

QuickLookR – A macOS QuickLook plugin for R Data files

I had tried to convert my data-saving workflows to feather but there have been issues with it supporting large files (that seem to be near resolution), so I’ve been continuing to use R Data files for local saving of processed/cleaned data. I make many of these files and sometimes I do it as a one-off... Continue reading...

U.S. Drought Animations with the “Witch’s Brew” (purrr + broom + magick)

This is another purrr-focused post but it’s also an homage to the nascent magick package (R interface to ImageMagick) by @opencpu. We’re starting to see/feel the impact of the increasing drought up here in southern Maine. I’ve used the data from the U.S. Drought Monitor before on the blog, but they also provide shapefiles and...

Use quick formula functions in purrr::map (+ base vs tidtyverse idiom comparisons/examples)

July 26, 2016
By

I’ve converted the vast majority of my *apply usage over to purrr functions. In an attempt to make this a quick post, I’ll refrain from going into all the benefits of the purrr package. Instead, I’ll show just one thing that’s super helpful: formula functions. After seeing this Quartz article using a visualization to compare... Continue reading...

Mid-year R Packages Update Summary

July 24, 2016
By

I been updating some existing packages and github-releasing new ones (before a CRAN push). Most are “cyber”-related, but there are some general purpose ones. Here’s a quick overview: docxtractr (CRAN, now, v0.2.0) was initially designed to make it easy to get data tables out of MS Word (docx) documents. The update removes use of a... Continue reading...

Slaying CIDR Orcs with Triebeard (a.k.a. fast trie-based ‘IPv4-in-CIDR’ lookups in R)

July 12, 2016
By

The insanely productive elf-lord, @quominus put together a small package (triebeard) that exposes an API for radix/prefix tries at both the R and Rcpp levels. I know he had some personal needs for this and we both kinda need these to augment some functions in our iptools package. Despite triebeard having both a vignette and... Continue reading →

CRAN Packages on GitHub (and some CRAN DESCRIPTION observations)

July 10, 2016
By

Just about a week ago @thosjleeper posited something on twitter w/r/t how many CRAN packages had associations with GitHub (i.e. how many used GitHub for development). The DESCRIPTION file (that comes with all R packages) has some fields that can house this information and most folks who do use GitHub for development of R seem... Continue reading →

Bridging The Political [Polygons] Gap with ggplot2

The @pewresearch folks have been collecting political survey data for quite a while, and I noticed the visualization below referenced in a Tableau vis contest entry: Those are filled frequency polygons, which are super-easy to replicate in ggplot2, especially since Pew even kind of made the data available via their interactive visualization (it’s available in...

Making “Time Rivers” in R

Once again, @albertocairo notices an interesting chart and spurs pondering in the visualization community with his post covering an unusual “vertical time series” chart produced for the print version of the NYTimes: I’m actually less concerned about the vertical time series chart component here since I agree with TAVE* Cairo that folks are smart enough...
