+- [[#modifying-a-file][Modifying a file]]
+
+* To begin
+If you have never used git with RStudio, *we strongly advise that you
+follow [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/d132a854b0464ad29085cedaded23136][our tutorial on using git from RStudio]]* (/"RStudio et Gitlab"/
+). Before proceeding, make sure you also have followed the
+*[[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/7508aece244548349424dfd61ee3ba85]["git/GitLab configuration" tutorial]]*.
+
+Alternatively, you may want to watch [[https://www.youtube.com/embed/uHYcDQDbMY8][this video]] (in English). If you
+do not like videos, you should have a look at the [[https://swcarpentry.github.io/git-novice/14-supplemental-rstudio/index.html][step-by-step
+explanations from Software Carpentry]]. It comes with many screenshots
+and is quite progressive.
+
+* Cloning a repository
+Open RStudio and do the following steps:
+- Create a new version controled project: =File / New Project / Version Control=
+ #+BEGIN_CENTER
+ [[file:rstudio_images/new_project.png]]
+
+ [[file:rstudio_images/git.png]]
+ #+END_CENTER
+- Get the URL from your GitLab repository:
+ #+BEGIN_CENTER
+ [[file:rstudio_images/adresse_depot.png]]
+ #+END_CENTER
+- Indicate this URL in the "Repository URL" field (/you may want to
+ prefix this URL with =xxx@= where =xxx= is/ /your Gitlab id to avoid
+ repeatedly giving it later on/).
+ #+BEGIN_CENTER
+ [[file:rstudio_images/clone.png]]
+ #+END_CENTER
+- If you're behind a proxy, git should be configured
+ accordingly. Check the [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/7508aece244548349424dfd61ee3ba85]["Dealing with proxies" section]].
+- Git will then connect to Gitlab and fetch a whole copy of the
+ repository.
+- RStudio should restart in a mode related to Git:
+ #+BEGIN_CENTER
+ [[file:rstudio_images/rstudio.png]]
+ #+END_CENTER
+- The file manager on the right, allows you to browse the version
+ controled repository.
+* Modifying a file
+- Open =Module2/exo1/toy_document.Rmd= and perform a simple
+ modification.
+- Save
+- Go to the Git menu to commit
+ #+BEGIN_CENTER
+ [[file:rstudio_images/commit.png]]
+
+ [[file:rstudio_images/commit2.png]]
+ #+END_CENTER
+- Select the lines to commit and then click on =commit=
+ #+BEGIN_CENTER
+ [[file:rstudio_images/commit5.png]]
+ #+END_CENTER
+ Your modifications have now been commited on your local
+ machine. They haven't been propagated to GitLab yet.
+- Click on =push= to propagate them on GitLab
+ #+BEGIN_CENTER
+ [[file:rstudio_images/push.png]]
+
+ [[file:rstudio_images/push2.png]]
+
+ [[file:rstudio_images/push3.png]]
+ #+END_CENTER
+ *NB*: You won't be able to propagate your modifications on GitLab if
+ some modifications have been done on GitLab in the meantime.
+ [[file:rstudio_images/push4.png]]
+- You should first merge these remote modifications locally. Click on
+ =pull= to get these modifications on your machine.

+- [[#pour-commencer][Pour commencer]]
+- [[#Cloner-un-dépôt][Cloner un dépôt]]
+- [[#modifier-un-fichier][Modifier un fichier]]
+
+* Avant de commencer
+La première chose à faire est de configurer Git sur votre
+ordinateur. Pour ce faire, vous pouvez suivre la vidéo
+[[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/7508aece244548349424dfd61ee3ba85][configurer Git pour Gitlab]] et le document
+[[https://gitlab.inria.fr/learninglab/mooc-rr/mooc-rr-ressources/blob/master/module2/ressources/gitlab_fr.org][Git et Gitlab]] correspondant.
+
+Vous pourrez alors utiliser Git avec RStudio. Pour ce faire, vous
+pouvez suivre la vidéo [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/d132a854b0464ad29085cedaded23136][RStudio - Gitlab]] dont les étapes
+sont reprises ci-dessous.
+
+/(Nous vous signalons aussi cette/ [[https://www.youtube.com/embed/uHYcDQDbMY8][vidéo]] /(en anglais) ainsi que le/ [[https://swcarpentry.github.io/git-novice/14-supplemental-rstudio/index.html][tuto
+pas à pas]] /(en anglais) de Software Carpentry.)/
+
+* Cloner un dépôt
+Ouvrir RStudio et procéder comme suit :
+- Créer un nouveau projet sous contrôle de version : =File / New Project / Version Control=
+ #+BEGIN_CENTER
+ [[file:rstudio_images/new_project.png]]
+
+ [[file:rstudio_images/git.png]]
+ #+END_CENTER
+- Récupérer l'URL du dépôt Gitlab
+ #+BEGIN_CENTER
+ [[file:rstudio_images/adresse_depot.png]]
+ #+END_CENTER
+- Indiquez cette URL dans le champ "Repository URL" /(vous voudrez/
+ /peut-être préfixer cette URL avec =xxx@= où =xxx= est votre identifiant/
+ /Gitlab pour éviter d'avoir à le ressaisir ultérieurement)/.
+
+ #+BEGIN_CENTER
+ [[file:rstudio_images/clone.png]]
+ #+END_CENTER
+- Si vous êtes derrière un proxy, il faut le définir dans Git (voir le
+ paragraphe "Gérer les proxy" de la page sur [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/7508aece244548349424dfd61ee3ba85][Git et Gitlab]]).
+- Git se connecte à Gitlab et récupère une copie complète du dépôt.
+- RStudio redémarre dans un mode lié à Git :
+ #+BEGIN_CENTER

+
+* Installing RStudio
+** Linux (debian, ubuntu)
+We provide here only instructions for Debian-based distributions. Feel
+free to contribute to this document to provide up-to-date information
+for other distributions (e.g., RedHat, Fedora).
+
+Today, the stable versions of the most common distributions provide
+recent enough versions of R:
+- Debian (stretch) ships with [[https://packages.debian.org/stretch/r-base][R 3.3.3-1]], [[https://packages.debian.org/stretch/r-cran-knitr][knitr 1.15.1]], and [[https://packages.debian.org/stretch/r-cran-ggplot2][ggplot 2.2.1]]
+- Ubuntu (bionic 18.04) ships with [[https://packages.ubuntu.com/bionic/r-base][R 3.4.4]], and [[https://packages.ubuntu.com/bionic/r-cran-knitr][knitr 1.17]], and [[https://packages.ubuntu.com/bionic/r-cran-ggplot2][ggplot 2.2.1]]
+- Ubuntu (artful 17.04) ships with [[https://packages.ubuntu.com/artful/r-base][R 3.4.2]], and [[https://packages.ubuntu.com/artful/r-cran-knitr][knitr 1.15]], and [[https://packages.ubuntu.com/artful/r-cran-ggplot2][ggplot 2.2.1]]
+If your distribution is older than this, well, it may be a good time
+for upgrading...
+
+*** Installing R
+First, you need to install the R language and convenient packages
+by running (as root):
+#+BEGIN_SRC shell
+apt-get update ; sudo apt-get install r-base r-cran-knitr r-cran-ggplot2
+#+END_SRC
+
+Alternatively, if the installation of =r-cran-gplot2= or =r-cran-knitr=
+fails, you may want to install them locally (through the R packaging
+system) and manually by running the following commands in R (or
+RStudio):
+#+BEGIN_SRC R
+install.packages("knitr")
+install.packages("ggplot2")
+#+END_SRC
+
+If you plan to export pdf documents with LaTeX, you probably also want
+to run (as root):
+#+begin_src sh :results output :exports both
+apt-get update ; apt-get install texlive-base
+#+end_src
+
+*** Installing RStudio
+RStudio is unfortunately not packaged within Debian so the easiest is
+to download the corresponding Debian package on the [[https://www.rstudio.com/products/rstudio/download/#download][RStudio webpage]]
+and then to install it manually (you may have to adjust the version number in the following example). Here is how to install it:
+
+#+BEGIN_SRC shell
+cd /tmp/
+wget https://download1.rstudio.org/rstudio-xenial-1.1.453-amd64.deb
+sudo dpkg -i rstudio-xenial-1.1.453-amd64.deb
+sudo apt-get update ; sudo apt-get -f install # to fix possibly missing dependencies
+#+END_SRC
+** Mac OSX and Windows
+- Install R and Python following the instructions given in a [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/19c2b1de7766484bae73f3ab133463c6][separate resource]].
+- Download and install RStudio from the [[https://www.rstudio.com/products/rstudio/download/#download][RStudio webpage]] by choosing the right operating system.
+- Download and install MiKTeX from the [[https://miktex.org/download][MiKTeX webpage]] by choosing the right operating system. You will be prompted to install some specific packages when exporting to pdf.
+- Open RStudio and type the following commands in the console to install =knitr= and =ggplot2=:
+#+BEGIN_SRC R
+install.packages("knitr", dep=TRUE)
+install.packages("ggplot2", dep=TRUE)
+#+END_SRC
+* RStudio documentation
+The RStudio team has created a lot of very good material and
+tutorials. You should definitively look at the [[https://www.rstudio.com/resources/cheatsheets/][Cheat sheets
+webpage]]. In particular you may want to have look at the following
+ones:
+- [[https://github.com/rstudio/cheatsheets/raw/master/rstudio-ide.pdf][The RStudio IDE]],
+- [[https://github.com/rstudio/cheatsheets/raw/master/rmarkdown-2.0.pdf][R Markdown]] (here is also a [[https://rmarkdown.rstudio.com/][nice step-by-step presentation of Rmarkdown]]),
+- The [[https://www.rstudio.com/wp-content/uploads/2015/03/rmarkdown-reference.pdf][R Markdown Reference guide]],

+- [[https://github.com/rstudio/cheatsheets/raw/master/data-transformation.pdf][Data transformation with dplyr]]
+In case it helps, here are some (sometimes outdated) French versions
+of these documents:

+* Installer RStudio
+** Linux (debian, ubuntu)
+Nous ne fournissons ici que des instructions pour les distributions
+ basées sur Debian. N’hésitez pas à contribuer à ce document en
+ fournissant des informations à jour sur les autres distributions
+ (RedHat, Fedora, par exemple).
+
+Aujourd'hui, les versions stables des distributions les plus courantes
+fournissent des versions assez récentes de R :
+- Debian (stretch) est livré avec [[https://packages.debian.org/stretch/r-base][R 3.3.3-1]], [[https://packages.debian.org/stretch/r-cran-knitr][knitr 1.15.1]], et [[https://packages.debian.org/stretch/r-cran-ggplot2][ggplot 2.2.1]]
+- Ubuntu (bionic 18.04) est livré avec [[https://packages.ubuntu.com/bionic/r-base][R 3.4.4]], [[https://packages.ubuntu.com/bionic/r-cran-knitr][knitr 1.17]], et [[https://packages.ubuntu.com/bionic/r-cran-ggplot2][ggplot 2.2.1]]
+- Ubuntu (artful 17.04) est livré avec [[https://packages.ubuntu.com/artful/r-base][R 3.4.2]], [[https://packages.ubuntu.com/artful/r-cran-knitr][knitr 1.15]], et [[https://packages.ubuntu.com/artful/r-cran-ggplot2][ggplot 2.2.1]]
+Si votre distribution est plus ancienne, c'est peut-être l'occasion de
+la mettre à jour...
+
+*** Installer R
+Pour commencer, vous devez installer le langage R et quelques packages
+en exécutant (à la racine) :
+#+BEGIN_SRC shell
+apt-get update ; sudo apt-get install r-base r-cran-knitr r-cran-ggplot2
+#+END_SRC
+
+Si l'installation de =r-cran-knitr= ou =r-cran-gplot2= échoue, vous pouvez
+également installer ces packages manuellement en exécutant les
+commandes suivantes sous R (ou RStudio) :
+#+BEGIN_SRC R
+install.packages("knitr")
+install.packages("ggplot2")
+#+END_SRC
+
+Si vous envisagez d'exporter des documents pdf avec LaTeX, il faudra
+probablement aussi exécuter (à la racine) :
+#+begin_src shell :results output :exports both
+apt-get update ; apt-get install texlive-base
+#+end_src
+
+*** Installer RStudio
+RStudio n’est malheureusement pas intégré à Debian. Le plus simple est
+ de télécharger le paquet Debian correspondant sur le [[https://www.rstudio.com/products/rstudio/download/#download][site RStudio]],
+ puis de l’installer manuellement (vous devrez peut-être adapter le
+ numéro de version) :
+
+#+BEGIN_SRC shell
+cd /tmp/
+wget https://download1.rstudio.org/rstudio-xenial-1.1.453-amd64.deb
+sudo dpkg -i rstudio-xenial-1.1.453-amd64.deb
+sudo apt-get update ; sudo apt-get -f install # to fix possibly missing dependencies
+#+END_SRC
+** Mac OSX and Windows
+- Installer R et Python en suivant les instruction dans une [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session02/jump_to_id/19c2b1de7766484bae73f3ab133463c6][ressource spécifique]].
+- Télécharger et installer RStudio depuis le [[https://www.rstudio.com/products/rstudio/download/#download][site RStudio]] en
+ choisissant le bon système d'exploitation.
+- Télécharger et installer MiKTeX depuis le [[https://miktex.org/download][site MiKTeX]] en choisissant le bon
+ système d'exploitation. Vous serez amené à installer différents
+ packages lors du premier export pdf.
+- Ouvrir RStudio et exécuter les commandes suivantes dans la console pour
+ installer =knitr= et =ggplot2=
+#+BEGIN_SRC R
+install.packages("knitr", dep=TRUE)
+install.packages("ggplot2", dep=TRUE)
+#+END_SRC
+* Documentation RStudio
+L’équipe de RStudio a créé différents matériels et tutoriels très bien
+faits. Nous vous recommandons de consulter les [[https://www.rstudio.com/resources/cheatsheets/][fiches mémo]]. En
+particulier, vous pourriez être intéressés par celles-ci :
