So, when you’re setting the position of text in ggplot, you may have to use the hjust and vjust commands. Depending on your demands, and if you don’t understand what they’re doing, they might seem hard to use. I found one script that...

Textual Healing Part II
Yesterday’s post showed a number of quick coding options for changing text in a basic ggplot. Here’s another two tricks for fine-tuning faceted plots. Again, let’s load our made up data about tooth growth (a real dataset in R, ToothGr...
Textual Healing
While I know there are several awesome guides for how to make fine-tuning adjustments to plot labels/axes/ticks/text in ggplot, this is still the most common question I get from people new to ggplot: how do I change the size/font/color/position of (som...
Can’t a plot catch a break(s)?
This post continues with the theme of how to modify plots from within ggplot; today we will specifically looking at custom axis breaks. Plots later in the week will examine the commands to change text in the plot area. The various other shortcomings o...
Another look at ideology of the US congress
In response to last week's post on the rapidly increasing ideology of the US Republican Party, Mike Lawrence suggested another way of looking at the DW-NOMINATE ideology data. Rather than simply looking at boxplots of the congress scores by party over time, we could fit a smooth curve to get a better sense of the trends over time. Mike...
Plotting letters as shapes in ggplot2
This post is a little more esoteric than most, but I found myself needing to solve this problem, so I’m just passing the solution on to you. The plot above shows the distribution of DW-NOMINATE scores for the 18th Congress, with party indicated ...
GGtutorial: Day 5 – Gradient Colors and Brewer Palettes
So, continuing with the short tutorials on how to do relatively simple (but sometimes very frustrating things) in ggplot, today’s post looks at how to use gradient colors and Brewer colors to color either continuous or discrete dependent variab...
Watch Obama and Romney criss-cross the US
The Washington Post has an interactive graphic showing the rate at which the US presidential candidates Barack Obama and Mitt Romney have visited the various states for campaign rallies and fundraisers. Here's how it looks today: You can clearly see the focus on key swing states like Florida and Ohio, as well as non-competitive (but donor-rich) states like California...
Tracking Hurricane Sandy with Open Data and R
Hurricane Sandy is shaping up to be a major, and very dangerous, meteorological event for the US's East coast. Naturally, everyone is looking for the latest information and forecasts. Fortunately, the wealth of public meteorological data available on the open web, combined with real-time on-the-ground updates via social media, means that an ecosystem of on-line apps is now available...
Plotting correlation ellipses
This is an oldie but a goodie. There are a lot of ways to plot multiple bivariate relationships, but this is one of my favorites, courtesy of the R Graph Gallery. https://gist.github.com/819111
