You can install RStudio on Ubuntu by downloading it directly from the RStudio website. Here's a step-by-step guide: 1. **Install R**: RStudio is an IDE for R, so you first need to install R. Open terminal, and paste the following commands: ``` sudo apt update sudo apt install r-base ``` After running these commands, you should have R installed. You can verify this by running `R --version` in your terminal. 2. **Download RStudio**: Visit the RStudio download page at `https://www.rstudio.com/products/rstudio/download/#download` and download the appropriate version for your system. Assuming you are running a 64-bit system, you would select "RStudio x.yy.zz - Ubuntu 18/Debian 10 (64-bit)". 3. **Install RStudio**: Once the download is completed, navigate to your download directory. You should see a .deb file for RStudio. Install it by running: ``` sudo dpkg -i rstudio-x.yy.zz-amd64.deb ``` Replace "x.yy.zz" with the version you downloaded. If you face any missing dependencies issue, run `sudo apt --fix-broken install` to resolve it and then retry the above command. After following these steps, you should have RStudio installed. You can launch it by typing `rstudio` in your terminal.
