Hi Graham,
However, I am not at all sure what to do with the other two files (Rdaemon and R,app) as these don't unzip to bundle files.
Fair enough! Looks like those other files *are* zip files but lacked the extension. To get the Rdaemon version running rename "R" to "R.zip" and then double click it. You should see
R Console (Rdaemon).tmbundle
which can then be double clicked to add it to TextMate.
Now open a new file, change the language to "R Console (Rdaemon)" from the selector at the bottom of the window. Type
start[tab]
and the daemon should start. There might be a small bug here in that you'll see two ">" signs. Just delete one of them and begin to enter R commands as you would in the console.
If I type "test<-c(3,4, 6, 7, 8, 9, 10)" in TextMate and hit command R, An R runtime opens and the command is executed and this line appears in the runtime.
I would now expect to type "test" in Textmate, hit command R again and get something like:
test
[1] 3 4 6 7 8 9 10
This should now work as you expect. It's a really nice environment!
Good luck, Paul
