Dear Steve,
thank you for your answer. I tried the following: (1) I went to "Bundles" => "Bundle Editor" => "Show Bundle Editor" (2) navigated to "R Console (R.app)" => "Send Document / Selection to R.app" (3) created a copy and called it "Send all before cursor to R.app" (4) for this new command, I went to "Command(s)" and replace the line saying: rawText="`cat`" by: rawText = "`head -$(($TM_LINE_NUMBER-1))`" as you suggested (5) I used the "Key Equivalent" "shift + apple-key + R"
Now when I executed the command, a lot of weird things happened [I work with Version 1.5.8 (1505) on Mac OS X 10.6.7]: 1) A window pops up, saying "Sending task to Rdaemon.." and then "Rdaemon is busy..." and it seems that every line of the file is sent ... 2) A new file named "console.Rcon -- Rsession" popped up. It had two tabs: The first one is labelled "console.Rcon" and contains the sign ">", the second one is called "r_res" and is empty. 3) nothing is executed in R [R is also not opened etc].
Do you know what's going wrong?
Cheers,
Marius
