The first edition of The R Book by Michael J. Crawley was an ambitious work, but managed to be slightly rubbish due to the atrocious typographical layout of the original book. The good news is that the new 2nd edition, released in 2013, has a substanti...

Generating polygon boundaries for plotting simple time series data with missing data
Every so often I want to plot some data with pretty upper and lower error bounds, such as temperature data through time, perhaps with the maximum and minimum temperature range or standard error bounds for averaged data. The polygon( ) function can make those sorts of pretty plots. However, I’ll often have chunks of missing
The new definitive guide for setting up Eclipse, StatET, and R on Windows 7
Quite a while back I wrote some tutorials on getting the StatET plugin for Eclipse running, so that you can write R code and run it within the Eclipse development environment. The developers of all of these pieces of software have kept marching on with...
Adding p values and R squared values to a plot using expression()
I was fooling around with including a p-value and R2 value on a plot I was putting together, and found myself quickly descending into the world of R graphics esoterica. I wanted to be able to include the values on the fly using values extracted from a ...
Another R + iButton script
Previously I’ve detailed R scripts that automate the launching and downloading Maxim iButton thermochron data loggers. I’m typically doing the launching and downloading at separate times in my workflow, since I have duplicate iButtons to swap out, so separate scripts work for me. Ryan Knowles recently contributed a combined version of these scripts that downloads
R scripts for downloading iButton Thermochron dataloggers
Last time, I posted some R code to help quickly launch many iButton Thermochron temperature dataloggers with the same mission parameters. The R code makes use of a publicly-available command line utility released by the iButton’s manufacturer, Maxim. Of course, Maxim also has a command line utility for downloading the data from those iButtons that
Launching iButton Thermochrons with the help of R
Maxim's iButton Thermochron temperature dataloggers are little silver doo-dads the size of a large watch battery that can record up to 2048 time-stamped temperature values. The internal battery is usually good for a few years of use. Maxim supplies a J...
Plotting stuff on an image
Recently, I needed to figure out how many extension cords I was going to need to buy in order to reach parts of my field site. Wandering around in the field with a surveyor's tape was an option, but so was plotting distances on an aerial image I had of...
Eclipse and StatET 2.0 Install For Running R
The Eclipse IDE with StatET plugin, developed by Stephen Wahlbrink, is one of the more (maybe the most) full-featured options for running R. I’ve written about this combination before (previous post), but the highlights include a script editor with syntax highlighting, code completion, an integrated graphics window, an advanced debug system, and the best object
Loading OSU’s VGPM ocean productivity data in R
Oregon State University makes a set of ocean productivity data derived from satellite data available for download and use by researchers. The Ocean Productivity website explains the available data and how it was derived. I have put together a few R fun...
