This error indicates that the system cannot find the Rscript command, even after you’ve installed R and verified your installation directory. The confusion usually arises from how the PATH variable is set up in your system.

Why Does This Error Occur?

The core of the issue lies in the $PATH variable, which is crucial for the command line to locate the programs you want to run. In your case, it seems that the Rscript command is not accessible because the path is set incorrectly.

Here's what you need to keep in mind:

You should check that you're using the correct syntax in setting the path, especially when using Git Bash on Windows.

Solution: Adjusting the PATH Variable

To solve the Rscript command not found error, follow these organized steps to correctly set your $PATH variable:

Step 1: Locate Rscript

Find the installation directory of R: This is generally located in the default installation folder. For example, it may be at C:/Program Files/R/R-4.3.0/bin/ for R 4.3.0.

Step 2: Modify the System Environment Variable

Open System Properties: Right-click on the Start Menu and select System, then click on Advanced system settings.

Access Environment Variables: In the System Properties window, click on the Environment Variables button located at the bottom right.

Edit PATH: In the "System variables" section, look for the Path variable and select it, then click Edit.

Add R's Bin Directory:

Click New and type in C:/Program Files/R/R-4.3.0/bin/ (make sure it ends with bin/).

Step 3: Verify Your Changes

Open a new Git Bash window: It’s important to open a new instance for the changes to take effect.

Step 4: Running Your Script

Now, navigate to the directory where your R script is located and try running it again with the command:
