You can enlarge any page by clicking on the = box. In this case it will occupy all left or right
pane. You can manually enlarge with of the pane by dragging the border. Actually it makes sense to make
left pane wider then the right during debugging and vise versa when viewing graphic results.
You work in RStudio from opening it to closing it is called session. When you try to close RStudio
it asks you whether to save session. If you answer yes the configuration of windows, you Tools/Global_options
settings, history of command and several other things are saved in a special file and are restored
when you open RStudio again.
Like in Visual Studio you can group several functions and data in RStudio in so called projects.
A project, which is a folder in filesystem with a several special files, written to it by RStudio.
In other words a project is a collection of files— R scripts and data file as well as results
and graphs — that are all related to each other and stored in its own working directory. This agreement
help to keep your files organized.
When project is opened those special files are loaded automatically creating environment that is
close to the one you used to have when you last close the project.
Creating or opening RStudio project also sets R working directory. You do not need to set it separately
using
| Creating or opening RStudio project also sets R working directory. You do not need to set
it separately |
You can create an RStudio project:
- In a brand new directory
- In an existing directory where you already have R code and data
- By cloning a version control (Git or Subversion) repository
To create a new project use the Create Project command (available on the Projects
menu and on the global toolbar):
When a new project is created RStudio:
- Creates a project file (with the extension.Rproj ) in the project directory.
This file contains various project options and can also be used as a shortcut for opening the project
directly from the filesystem.
- Creates a hidden directory (named .Rproj.user ) where project-specific temporary
files (e.g. auto-saved source documents, window-state, etc.) are stored. This directory is also
automatically added to .Rbuildignore, .gitignore, etc. if required.
- Loads the project into RStudio and display its name in the Projects toolbar (which is
located on the far right side of the main toolbar)
There are several ways to open a project:
- Using the Open Project command (available from both File/OpenPrject and the
Projects toolbar ( at the very right of the icon toolbar) to browse for and select an existing project
file (e.g. MyProject.Rproj).
- Selecting a project from the list of most recently opened projects (also available from both
the Projects menu and toolbar).
- Double-clicking on the project file within the system shell (e.g. clicking on file Windows Explorer).
When a project is opened within RStudio the following actions are taken:
- A new R session (process) is started
- The .Rprofile file in the project's main directory (if any) is sourced by R
- The .RData file in the project's main directory is loaded (if project options indicate
that it should be loaded).
- The .Rhistory file in the project's main directory is loaded into the RStudio History
pane (and used for Console Up/Down arrow command history).
- The current working directory is set to the project directory.
- Previously edited source documents are restored into editor tabs
- Other RStudio settings (e.g. active tabs, splitter positions, etc.) are restored to where they
were the last time the project was closed.
When you are within a project and choose to either Quit, close the project, or open another project
the following actions are taken:
- .RData and/or .Rhistory are written to the project directory (if current options
indicate they should be)
- The list of open source documents is saved (so it can be restored next time the project is opened)
- Other RStudio settings (as described above) are saved.
- The R session is terminated.
You can work with more than one RStudio project at a time by simply opening each project in its own
instance of RStudio. There are two ways to accomplish this:
- Use the Open Project in New Window command located on the Project menu.
- Opening multiple project files via the system shell (i.e. double-clicking on the project file).
There are several options that can be set on a per-project basis to customize the behavior of RStudio.
You can edit these options using the Project Options command on the Project
menu:
R command line provides access to help. try ?[function] or ??"[topic]"
This is different from an R session, which is all the objects and work done in
R and kept in memory for the current usage period, which usually resets upon restarting
R.
The simplest way to start a new project is to click File >> New Project
You will be presented with the initial menu that contains three option. The simplest is to start
project using a directory. As you can see three options are available: starting a new project in a new
directory, associating a project with an existing directory or checking out a project from a version
control repository such as Git or SVN. In all three cases a .Rproj file is put into the
resulting directory to keeps track of the project.
Choosing to create a new directory brings up a dialog, that requests a project name and where to
create a new directory.
Choosing an existing directory asks for the name of the directory:
This way you can convert existing directory with data and R scripts into a project.
There are also options to use GIT or other version management system, but we will omit this
option for now.
When typing code, such as an object name or function name, hitting Tab will auto complete
the code. If more than one object or function matches the letters typed so far, a dialog will pop up
giving the matching options.
Editor function are listed in two tabs: Edit and Code. As you can see from Edit dialog of the main
upper bar of RStudio, the Edit tab contains more or less standard capabilities typical for most editors.
Code tab is more interesting. In it the built-in editor provide several interesting capabilities:
Among them:
- Insert Section (Ctrl-Shift-R)
- Go to File/function (Ctrl-.)
- Go to Function definition
- Reindent lines (Ctrl-I)
- Comment/Uncomment Lines (Chrl-Shift-C)
- Run Line Ctrl-Enter
- Re-Run line Ctrl-Shift-P
- Run region
- Source current editor buffer (Ctrl-Shift-S)
For a complete list of shortcuts click Help/Keyboard Shortcuts (Alt-Shift-K)
There are several ways to send and execute commands from the editor to the console.
- To execute one line place the cursor at the line and press
Ctrl+Enter.
- To execute a selection, simply highlight the selection and press
Ctrl+Enter.
- To run an entire code in the editor window, press
Ctrl+Shift+S.
Customarization of RStudio
RStudio is customizable via options in Tools/Global_Options:
General options. There is a control for selecting which version of R to use.
This is a powerful tool when a computer has a number of versions of R. However, RStudio
must be restarted after changing the R version. It is also a good idea to not restore
or save .RData files on startup and exiting. RData files are a convenient
way of saving and sharing R objects.
The Code Editing options, control the way code is entered and displayed in the
text editor. It is generally considered good practice to replace tabs with spaces, either two or four.
Users with strong Unix experience might benefit from vim mode.
Appearance options, change the way code looks, aesthetically. The font, size and color
of the background and text can all be customized here. The first thing to customize is size of the font
to display R programs in Tools/Global Options/Appearance. The default fond is Lucida Console
and its OK. The default fond size is 10 and its too small. I would recommend 11 or higher. With 10 it
is difficult to distinguish some symbols such as comma and dot.
The Pane Layout options, allow to specify which tabs upper left pane and lower right pane
should contain.
The Packages options allow specify you CRAN mirror, which is important if you in network environment
with proxy. You can pick up the mirror that is geographically the closest and reliable
Sweave option allow you to choose between using Sweave or knitr. Both are used for the
generation of PDF documents with knitr also enabling the creation of HTML
documents. knitr might be the better option, although it must first be installed. This
is also where the PDF viewer is selected.
RStudio contains a spelling checker for writing LATEX and Markdown documents (using knitr,
preferably), which is controlled from the Spelling options. Not much needs to be set here.
The last option, Git/SVN, indicates where the executables for Git and SVN exist. This needs to be
set only once but is necessary for version control.
RStudio Server v0.99 requires RedHat or CentOS version 5.4 (or higher) as well as an installation of R. You can install R for RedHat
and CentOS using the instructions on CRAN: https://cran.rstudio.com/bin/linux/redhat/README
.
RedHat/CentOS 6 and 7

RStudio is a relatively new and shiny editor for R. It's easy to use, it has
a decent Help page, it has very good support, and it incorporates R in a practical way. Of course,
you're free to work with any text editor you like.
Installing RStudio is easy. Just follow these steps:
-
Go to RStudio Download.
-
Click the Download RStudio Desktop button.
-
Select the installation file for your system.
-
Run the installation file.
RStudio will be installed on your system. It normally detects your latest installed R version
automatically. If you didn't do anything funky, you should be able to use R from within RStudio without
extra configuration.
You may want to use a different R version from the one RStudio detected. For example, you may
want to use R in a 64-bit context. Or RStudio may not have recognized your installation of R. In
that case, you can set which R version to use by choosing Tools→Options to open the Options pane.
To change the R version, click the Change button. Then you can switch between the default 32-bit
R installation or the 64-bit R installation (if installed), or you can choose a specific version
of R. (RStudio lists all the versions it can find.)
If you click Browse, you can select the root directory for any R version you want to use. This
folder normally looks something like …/R/R-n.n.n. If you select an R version that has both 32-bit
and 64-bit builds, RStudio will ask you which build you want to use.
In the Options pane, you also can tweak the behavior of R in RStudio. If you click the General
icon in the left column, you get all the default options for R in RStudio:
-
Initial working directory: You can set the default working directory R will use at startup.
-
Save workspace to .RData on exit: Your options are Ask, Never, or Always. By default,
RStudio asks you whether you want to save the workspace when you quit.
-
Restore .RData into workspace at startup: Select this check box to let RStudio restore
the workspace automatically at startup. RStudio will look for a saved workspace in the root folder
or the default working directory.
-
Always save history (even when not saving .RData): Select this check box to have RStudio
always save the history. If you don't select this check box, RStudio doesn't save the history
when you exit the program.
-
Use single global history (rather than per-working directory): Select this check box
to have RStudio always save the history in a single global file.
-
Remove duplicate entries in history: If you select this check box, RStudio removes duplicate
entries from your history when the history is saved.
-
Comprehensive R Archive Network (CRAN) mirror: Click the Change button to set the CRAN
mirror site that RStudio uses to install new packages.
These settings work for R only from within RStudio. If you use R with another editor or by itself,
the settings in RStudio will have no effect.
