Download Tar.gz In R
RStudio is a free and open-source integrated development environment for R, a programming language for statistical computing and graphics.
RStudio is available in open source and commercial editions on the desktop (Windows, Mac, and Linux) and from a web browser to a Linux server running RStudio Server or RStudio Server Pro.
How to install RStudio Desktop 1.2.1335 (Open Source License) on Ubuntu 18.04 using Tarball?
Step 1 — Download tarball from Rstudio website
Download rstudio-1.2.1335-amd64-debian.tar.gz from Rstudio Official Website (147.8 MB file size) into ~/Download directory.
Step 2 — Extract tarball into /opt/rstudio
$ sudo mkdir -p /opt/rstudio $ sudo tar xfvz ~/Downloads/rstudio-1.2.1335-amd64-debian.tar.gz --directory /opt/rstudio Step 3 — Create symlink latest
$ cd /opt/rstudio/ $ sudo ln -s /opt/rstudio/rstudio-1.2.1335 latest 
Figure-1: Setup symlink "latest" to point to rstudio-1.2.1335.
Why do you need symlink latest?
-
Symlink latestalways tracks current version of RStudio installation. -
Tomorrow, let us say, a new version 1.3.1 arrives, then install that version. Now you remove
symlink latestpointing to older version 1.2.1335, by issuing the following command:$ sudo unlink /opt/rstudio/latestSymlink latestpoints to current version rstudio-1.2.1335 but the arrival of newest version 1.3.1 causes to severe thesymlink latestfrom pointing to version 1.2.1335. -
Now create
symlink latestpointing to newer version 1.3.1 with the following command:$ cd /opt/rstudio/ $ sudo ln -s /opt/rstudio/rstudio-1.3.1 latestNow
symlink latestpoints to newer version rstudio-1.3.1. Note: There is no such version called 1.3.1, this is just afictionalone used to demonstrate the power ofsymlink latest. -
At the same time, you may still retain older versions without removing them. For some reasons you want to work on specific older version, you simply switch
symlink latestpointing that older version and that is it! You don't have to change any other settings. -
In step-4 appearing subsequently, you will be setting up
RHOME,PATHandLD_LIBRARY_PATHenvironement variables. As the values of this environment variables involvesymlink latest, so that even you switch pointing to newer versions in future, these settings always remain unchanged and untouched!
Step 4 — Create RStudio Environment Variables PATH, etc.
To set RStudio environment variables, create a new file in the /etc/profile.d directory.
$ sudo touch /etc/profile.d/rstudio.sh $ sudo vi /etc/profile.d/rstudio.sh Then copy and paste the following lines into the file:
#!/bin/bash export RHOME=/opt/rstudio/latest export PATH=/opt/rstudio/latest/bin:${PATH} export LD_LIBRARY_PATH=/opt/rstudio/latest/lib:${LD_LIBRARY_PATH} Save and close the file. Make it executable using the following command.
$ sudo chmod +x /etc/profile.d/rstudio.sh Then, set the environment variables permanently by running the following command:
$ source /etc/profile.d/rstudio.sh To verify PATH is correctly set, issue the following command:
$ echo $PATH 
Figure-2: PATH environment variable is set properly to "/opt/rstudio/latest/bin".
To verify LD_LIBRARY_PATH is correctly set, issue the following command:
$ echo $LD_LIBRARY_PATH 
Figure-3: LD_LIBRARY_PATH environment variable is set properly to "/opt/rstudio/latest/lib".
Step 5 — RStudio requires R 3.0.1+
If you don't already have R, follow the instructions:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 $ sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/' $ sudo apt update $ sudo apt install r-base To know the version of R, issue the following command:
$ R --version 
Figure-4: R version is 3.6.0.
Step 6 — RStudio IDE
You may invoke RStudio IDE from command line as shown below:
$ rstudio This command will take you to the Integrated Development Environment of RStudio.
Figure-5: Command "rstudio" takes you to RStudio IDE.
Step-7: Create shortcut launcher desktop icon.
Create and install a new desktop file called rstudio.desktop which is a shortcut for RStudio.
$ cd ~ $ vi rstudio.desktop Copy & Paste the following content into the file:
[Desktop Entry] Name=RStudio Type=Application Exec=/opt/rstudio/latest/bin/rstudio Terminal=false Icon=/opt/rstudio/latest/rstudio.png Comment=Integrated Development Environment NoDisplay=false Categories=Development;IDE; Save and exit from the editor.
Now, run the following command to install shortcut file in /usr/share/applications/ directory:
$ sudo desktop-file-install rstudio.desktop Now, you can click RStudio shortcut launcher icon from Dash to enter RStudio IDE.
Figure-6: "RStudio" shortcut launcher icon is shown in redbox on Dash desktop screen.
NOTE-1: With this, installation of RStudio Desktop v1.2.1335 (open source License) is complete.
This is where my Answer to the Post of Questioner SteveS ends. You may quit now.
NOTE-2: If you want to install RStudio Server v1.2.1335 (open source License), then you should go to next step-8, otherwise please quit now.
Step-8: How to install RStudio Server v1.2.1335 (Open Source License)?
RStudio Server enables you to provide a browser based interface to a version of R running on a remote Linux server, bringing the power and productivity of the RStudio IDE to server-based deployments of R.
To download RStudio Server, execute the following commands:
$ cd ~ $ sudo apt-get install gdebi-core $ wget https://download2.rstudio.org/server/bionic/amd64/rstudio-server-1.2.1335-amd64.deb Note: You may choose to verify the build's GPG signature prior to installing it.
Obtaining the Public Key
In order to validate a build's signature, you must first import and trust RStudio's public code-signing key. You can obtain the public key from a keyserver using gpg at the command line:
$ gpg --keyserver keys.gnupg.net --recv-keys 3F32EE77E331692F gpg: key 3F32EE77E331692F: public key "RStudio, Inc. (code signing) <info@rstudio.com>" imported gpg: Total number processed: 1 gpg: imported: 1 Validating Build Signatures
Issue the dpkg-sig command to validate the signature. Note: You may need to install the dpkg-sig package if it isn't already installed.
$ dpkg-sig --verify rstudio-server-1.2.1335-amd64.deb Processing rstudio-server-1.2.1335-amd64.deb... GOODSIG _gpgbuilder FE8564CFF1AB93F1728645193F32EE77E331692F 1553752985 To install RStudio Server v1.2.1335, execute the following command:
$ sudo gdebi rstudio-server-1.2.1335-amd64.deb Issue the following command to verify that RStudio Server is up and running:
$ sudo systemctl status rstudio-server.service 
Figure-7: The status command displays "RStudio server 1.2.1335" is up and running.
By default RStudio Server runs on port 8787 and accepts connections from all remote clients. After installation you should therefore be able to navigate a web browser to the following address to access the server:
http://<server-ip>:8787 Since Server and client are in the same machine, you can use http://localhost:8787 to access RStudio server, as shown below:
Figure-8: Supply your usual Ubuntu system username and password to logon to RStudio Server through Web.
RStudio will prompt for a username and password, and will authenticate the user by checking the server's username and password database.
After authentication and logon to RStudio server is successful, you can access IDE through Web as shown below:
Figure-9: After successful logon to RStudio Server, IDE is accessible now through Web.
