(v3.7.0) R: svtools

Maintainer: LCD 47 lcd047@gmail.com

This is a checker for R files, using the R package svTools (which, in turn, delegates most of the work to the checkUsage() function in the codetools package).

Security

This checker executes parts of 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:

let g:syntastic_enable_r_svtools_checker = 1

There is also a buffer-local version of this variable, that takes precedence over it in the buffers where it is defined.

Please note that setting this variable doesn't automatically enable the checker, you still need to add svtools to g:syntastic_r_checkers if you want to use it.

Limitations

svTools version 0.9-4 (current at the time of this writing) has a number of problems that prevents it from checking most sources. You might consider applying this patch as a workaround.

At the time of this writing, svTools doesn't produce meaningful column numbers (the column numbers are always set to 1). The patch mentioned above enables svTools to produce more useful column numbers, but only for syntax errors. If you apply the said patch and you're checking files containing tab characters, Vim's tabstop must match R's idea of tabstop, otherwise column numbers will be shifted. At the time of this writing R's tabstop is hardcoded to 8, so you should probably add something like this to your vimrc:

set tabstop=8

Note

This checker doesn't call the makeprgBuild() function, and thus it ignores the usual g:syntastic_r_svtools_<option> variables. The only exception is g:syntastic_r_svtools_exec, which can still be used to override the R executable.
