How to push git repository through ssh using git2r?

问题

I'm trying to use git2r package (version 0.21.0).
I always use ssh connexions in my projects (GitHub and GitLab hosted): I can do git pull/push with both RStudio IDE and command line.
I have a standard Ubuntu Xenial configuration; my keys are stored in ~/.ssh with standard names, my ssh-agent is running, and keys were added to ssh-agent. My problem is how to use the git2r package to push with ssh?

Here's what I do with a very basic workflow (work on master, remote name is origin):

library(git2r)
repo <- init("path_to_clone")
remote_url(repo)

[1] "git@gitlab.com:account/repository.git"

credentials <- cred_ssh_key()
str(credentials)

Formal class 'cred_ssh_key' [package "git2r"] with 3 slots
  ..@ publickey : chr "/home/user/.ssh/id_rsa.pub"
  ..@ privatekey: chr "/home/user/.ssh/id_rsa"
  ..@ passphrase: chr(0)

# some work, add(), commit()...
push(repo, "origin", "refs/heads/master", credentials = credentials)

 Error in .local(object, ...) : 
   Error in 'git2r_push': unsupported URL protocol

Is ssh protocol implemented in git2r package? Is there something I missed?`

Edit: I missed something, for sure. But, what?

libgit2_features()

$threads
[1] FALSE
$https
[1] FALSE
$ssh
[1] FALSE

I finally found what I missed. I forgot to install libssh2-1-dev library before installing git2r.
A similar question here.

Install libssh2-1-dev:

sudo apt-get install libssh2-1-dev
