February 11, 2016 | hrbrmstr

High resolution and SVG versions of the new R logo are finally available. I converted the SVG to WKT (file here) which means we can use it like we would a shapefile in R. That includes plotting! Here’s a short example of how to read that WKT and plot ...

February 10, 2016 | hrbrmstr

When you visit a site like the LA Times’ NH Primary Live Results site and wish you had the data that they used to make the tables & visualizations on the site: Sometimes it’s as simple as opening up your browsers “Developer Tools” console and looking for XHR (XML HTTP ...

Alternate R Markdown Templates

February 4, 2016 | hrbrmstr

The knitr/R markdown system is a great way to organize reports and analyses. However, the built-in ones (that come with RStudio/the rmarkdown package) rely on Bootstrap and also use jQuery. There’s nothing wrong with that, but the generated standalone HTML documents (which are a great way to ... [Read more...]

Cobble XPath Interactively with the xmlview Package

January 13, 2016 | hrbrmstr

(If you don’t know what XML is, you should probably read a primer before reading this post,) When working with data, one inevitably comes across things encoded in XML. I’m in the “anti-XML” camp, but deal with my fair share of XML in “cyber” and help out enough ...

The Force: Accounted, in R

January 9, 2016 | hrbrmstr

Despite being a cybersecurity professional, it’s pretty easy to social engineer me: https://t.co/R3qVHEMTLo @hrbrmstr is there an R package? ;)— Thorsten G. (@SaThaRiel74) January 8, 2016 I’ll note that @jayjacobs does it all the time to me. I took Thorsten’s tweet as a challenge to ggplot2... [Read more...]

World Map Panel Plots with ggplot2 2.0 & ggalt

December 29, 2015 | hrbrmstr

James Austin (@awhstin) made some #spiffy 4-panel maps with base R graphics but also posited he didn’t use ggplot2 because: …ggplot2 and maps currently do not support world maps at this point, which does not give us a great overall view. That is certainly a box I would not ...

Using MonetDB[Lite] with real-world CSV files

November 11, 2015 | hrbrmstr

MonetDBLite (for R) was announced/released today and, while the examples they provide are compelling there’s a “gotcha” for potential new folks using SQL in general and SQL + MonetDB + R together. The toy example on the site shows dumping mtcars with dbWriteTable and then doing things. Real-world CSV files ... [Read more...]

An Ephemeral Update to daylight()

November 2, 2015 | hrbrmstr

This occurrence of the bi-annual corruption of the space-time continuum (i.e. changing to/from standard/daylight time) in the U.S. caused me to make a slight change to the code from an older post. The daylight() function now auto-discovers the date and location information (via telize) from the ...

Less Drama, More Encoding

October 24, 2015 | hrbrmstr

Junk Charts adeptly noted and fixed this excessively stylized chart from the WSJ this week: Their take on it does reduct the ZOMGOSH WE ARE DOOMED! look and feel of the WSJ chart: But, we can further reduce the drama by using a more neutral color encoding and encode both ...

Installing R on OS X – “100% Homebrew Edition”

October 22, 2015 | hrbrmstr

In a previous post I provided “mouse-heavy” instructions for getting R running on your Mac. A few of the comments suggested that an “all Homebrew” solution may be preferable for some folks. Now, there are issues with this since getting “support” for what may be R issues will be very ... [Read more...]

Installing R on OS X

October 20, 2015 | hrbrmstr

I was in a conversation with an academic colleague (wicked smart dude) and the subject of installing R came up (NOTE: this will happen to you, too, if you ever have the misfortune to have a face-to-face convo with me ;-). They noted that getting up and running with R ...

Replicating NatGeo’s “Proper” Earthquake Map in R

October 4, 2015 | hrbrmstr

I saw this post over at NatGeo over the weekend and felt compelled to replicate this: with ggplot2. Three shapefiles later and we have it close enough to toss into a post (and I really don’t believe the continent names are necessary). library(rgdal) library(ggplot2) library(ggthemes)   # grab ...
