The ‘R’ Sessions

(Image from

A few years ago whilst working on my MSc thesis I was heavily into R a statistical analysis package which has a functional language feel to it. My friend Marc Hasenbank, a few others and I ran a series of workshops for people wanting an introduction to R. I recently wanted to show this to someone so thought I would post a link. The code from the tutorials can be found here


Using TextMate with R


I’ve been using the R language for some years now but didn’t have it installed on my current machine.

TextMate is a great editor to use as it has a custom bundle that gives you syntax highlighting and executes commands for you in the R console.

To install the R bundle:

cd ~/Library/Application\ Support/TextMate/Bundles/
svn co

Then in TextMate choose Bundles->Bundle Editor->Reload Bundles.

There is one tweak I make which is that I like to press ⌘ + RETURN to execute the current selection in the R console. So edit the bundle and find in the commands and change the key. Also I like it to return back to text mate afterwards, so I add the following to the script:

-e ‘tell application “TextMate” to activate’ \

I also removed the line about setting the current dir. This was a little fiddly – I found that I had to make sure I selected the entire line and cut it then delete, making sure there are no end of line characters. So it looks like this:

# input is selection or document
if [[ ${#TM_DIRECTORY} -gt 0 ]]; then
osascript -e ‘on run(theCode)’ \
		  -e ‘tell application “R” to activate’ \
		  -e ‘tell application “R” to cmd (item 1 of theCode)’ \
		  -e ‘tell application “TextMate” to activate’ \
		  -e ‘end run’ — “$rawText” “$curDir”

All good.

UPDATE: 07/02/2011 – R now comes with a 64bit version so if you are on a macbook you can replace “R” in the code above with “R64”
