How to find if file has changed using git2r

Say I have a repository repo:

library(git2r)
repo <- repository(".")

In this repository is a subdirectory R, with files a.txt, b.txt and other files that I'm not interested in. How can I use git2r to work out if there are unstaged changes in these files? I've looked at summary(diff()), but that works on the level of the whole repo.

Essentially, what I'm trying to do is replicate the effects of the git command:

! git diff-index --quiet HEAD -- file

Where if there are changes in the file, then return false. While I could use a system command, there's no guarantee the user has git in their path and so the command would fail.

Is there a way to replicate the git functionality I'm looking for?

This issue is solved in the latest development release of git2r. There is now an all_unstaged option to status:

> status(repo, all_untracked = TRUE)
Untracked files:
    Untracked:  untracked/a.txt
    Untracked:  untracked/b.txt
