" Vim syntax file

" Last Change: 2006 M<>r 06
|
|||
|
|
" 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
|
|||
|
|
|
|||
