Parent dir path in R

In R, you can get the parent directory path using the dirname() function. This function takes a file path as an argument and returns the directory (or parent directory) of that file. Here's an example:

file_path <- "/Users/MyUser/Documents/R_scripts/myscript.R"
parent_dir_path <- dirname(file_path)
print(parent_dir_path)

Output:

[1] "/Users/MyUser/Documents/R_scripts"

In the above example, dirname() function returns the parent directory of the file path (myscript.R).
