" This checker runs the code in your file.  This is probably fine if you
" wrote the file yourself, but it can be a problem if you're trying to
" check third party files.  If you are 100% willing to let Vim run the
" code in your file, set g:syntastic_enable_r_svtools_checker to 1 in
" your vimrc to enable this checker:
