Where does R store packages? 📦

If you are an R user, you might have wondered where R stores its packages 🤔. Whether you're a beginner or an experienced user, understanding how R stores packages can be helpful when managing and accessing them. In this blog post, we will answer two common questions related to this topic and provide easy solutions to address any issues you may encounter. Let's get started! 🚀

1. How do I find out what directory R has chosen to store packages? 🗂️

To find out the directory where R stores its packages, you can use the R.home() function. This function returns the root path of the current R installation. By appending the correct subdirectory, you can determine the package directory. In most cases, the package directory is located in the "library" subdirectory.

Here's an example of how you can find the package directory using R:

package_directory <- file.path(R.home(), "library")
package_directory

💡 Tip: Running the above code will give you the path to the package directory in your R installation. You can then navigate to that directory using the file explorer or execute further operations within R.

2. How can I change the directory in which R stores and accesses packages? 📁

Sometimes you may want to change the default directory where R stores and accesses packages. For example, you may have limited space on your current drive, or you might prefer to keep your packages organized in a specific location.

To change the package directory, you can use the .libPaths() function in R. This function allows you to set a new path where R should look for packages.

Let's say you want to change the package directory to a folder named "R-packages" located on your desktop. Here's how you can do it:

new_package_directory <- file.path("~/Desktop/R-packages")
.libPaths(new_package_directory)

💡 Tip: Running the above code will set the new package directory to the specified folder. Make sure to replace "~/Desktop/R-packages" with the desired path on your system.

Take control of your R packages! 🎛️

Now that you know how to find and change the package directory in R, you have more control over your R packages' storage and accessibility 🙌. If you were struggling with limited space or you simply wanted to keep your packages organized in a different location, these solutions should make your life easier.
