| " Vim syntax file |
| " Language: R Help File |
| " Maintainer: Johannes Ranke <jranke@uni-bremen.de> |
| " Last Change: 2006 Mรคr 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 |
| elseif exists("b:current_syntax") |
| finish |
| endif |
