" Usage:
"
" 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.
"
" A Makefile for producing R noweb files is in included in my Vim script
" R.vim:
" 	http://www.vim.org/scripts/script.php?script_id=1048
" You can also look in my SVN repository under:
" 	http://kri/viewcvs/*checkout*/Makefile.rnoweb?root=vim
"
"
" After selecting a visual block, 'r' sends it to the R interpreter
"
" Add to filetypes.vim, if you don't use vim 7
"   au BufNewFile,BufRead *.Rnw,*.rnw   setf rnoweb
" and/or
"   au BufNewFile,BufRead *.Snw,*.snw   setf rnoweb
