## Not run: 
## Initialize three temporary repositories
path_bare <- tempfile(pattern="git2r-")
path_repo_1 <- tempfile(pattern="git2r-")
path_repo_2 <- tempfile(pattern="git2r-")

dir.create(path_bare)
dir.create(path_repo_1)
dir.create(path_repo_2)

bare_repo <- init(path_bare, bare = TRUE)
repo_1 <- clone(path_bare, path_repo_1)
repo_2 <- clone(path_bare, path_repo_2)

config(repo_1, user.name = "Alice", user.email = "[e-mail]")
config(repo_2, user.name = "Bob", user.email = "[e-mail]")

## Add changes to repo 1
writeLines("Lorem ipsum dolor sit amet",
           con = file.path(path_repo_1, "example.txt"))
add(repo_1, "example.txt")
commit(repo_1, "Commit message")

## Push changes from repo 1 to origin (bare_repo)
push(repo_1, "origin", "refs/heads/master")

## Fetch changes from origin (bare_repo) to repo 2
fetch(repo_2, "origin")

## List updated heads
fetch_heads(repo_2)

## Checking out GitHub pull requests locally
path <- tempfile(pattern="ghit-")
repo <- clone("https://github.com/leeper/ghit", path)
fetch(repo, "origin", refspec = "pull/13/head:refs/heads/BRANCHNAME")
checkout(repo, "BRANCHNAME")
