+" Code written in vim is sent to R through a perl pipe
+" [funnel.pl, by Larry Clapp <vim@theclapp.org>], as individual lines,
+" blocks, or the whole file.
+
+" Press <F2> to open a new xterm with a new R interpreter listening
+" to its standard input (you can type R commands into the xterm)
+" as well as to code pasted from within vim.
+"
+" After selecting a visual block, 'r' sends it to the R interpreter
+"
+" In insert mode, <M-Enter> sends the active line to R and moves to the next
+" line (write and process mode).
+"
+" Maps:
+"       <F2>		Start a listening R interpreter in new xterm
+"       <F3>		Start a listening R-devel interpreter in new xterm
+"       <F4>		Start a listening R --vanilla interpreter in new xterm
+"       <F5>        Run current file
+"       <F9>        Run line under cursor
+"       r	        Run visual block
+"       <M-Enter>   Write and process
+
+" Only do this when not yet done for this buffer
+if exists("b:did_ftplugin")

+let b:did_ftplugin = 1

+" Disable backup for .r-pipe

+
+" Set tabstop so it is compatible with the emacs edited code. Personally, I
+" prefer shiftwidth=2, which I have in my .vimrc anyway
