How to Use file.choose() in R (With Example)

You can use the file.choose() function in R to bring up a file explorer window that allows you to interactively choose a file path to work with.

To use this function, simply type the following into your R console:


The following example shows how to use this function in practice.

Example: How to Use file.choose() in R

Suppose we have some file called df1.csv located in a folder called my_data_files that we’d like to import into our R environment:

However, suppose we don’t know the exact file path of this CSV file.

To quickly find it, we can type file.choose() into our R console:

A file explorer window will appear where we can then navigate to the folder that contains this file:

Note: If you don’t see the file explorer window, check to see if it opened behind RStudio.

When you double click on the file you’d like, the file path will automatically appear in your R console:

[1] "C:\\Users\\bob\\Documents\\my_data_files\\df1.csv"

You can then use this path to import the file into R:

#import df1.csv file
df <- read.csv("C:\\Users\\bob\\Documents\\my_data_files\\df1.csv")

#view result
