parent folder for working directory in r

To find the parent folder for the current working directory in R, you can follow these steps:

1. Use the getwd() function to get the current working directory. This function returns a character string representing the current working directory.

2. Use the dirname() function to extract the directory path from the working directory string obtained in the previous step. The dirname() function takes a path as input and returns the directory part of that path.

Here is an example code snippet that demonstrates these steps:

# Step 1: Get the current working directory
current_dir <- getwd()

# Step 2: Extract the parent folder
parent_folder <- dirname(current_dir)

# Print the parent folder
print(parent_folder)

The getwd() function retrieves the current working directory, which is stored in the current_dir variable. Then, the dirname() function is used to extract the parent folder from the current_dir variable, which is stored in the parent_folder variable. Finally, the print() function is used to display the parent folder.

This code will output the parent folder for the current working directory in R.
