In this R post you’ll learn how to find the names of system files using the system.file function.

Here’s how to do it.
Example 1: Find System Files of Base R Using system.file() Function
This section shows how to apply the system.file function to return the root of the base R package.
For this, we simply have to execute the system.file command without any additional specifications:
system.file() # Apply system.files function #  "C:/PROGRA~1/R/R-41~1.0/library/base"
As you can see based on the previous output of the RStudio console, we have returned the path to the base R package on my computer.
Example 2: Find System Files of Certain Package Using system.file() Function
The following R programming code illustrates how to return the path to a particular add-on package.
In this example, we’ll return the root of the dplyr package:
system.file( = "dplyr") # Apply system.files function #  "C:/Users/Joach/Documents/R/win-library/4.1/dplyr"
