" Vim syntax file
" Language: R Help File
" Maintainer: Johannes Ranke <jranke@uni-bremen.de>
" Last Change: 2006 Mär 01
" Version: 0.5
" Remarks: - Now includes R syntax highlighting in the appropriate
" sections if an r.vim file is in the same directory or in the
" default debian location.
" - I didn't yet include any special markup for S4 methods.
" - The two versions of \item{}{} markup are not
" distinguished (in the \arguments{} environment, the items to
" be described are R identifiers, but not in the \describe{}
" environment).
" - There is no Latex markup in equations
" Version Clears: {{{1
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
