rename a file in r

To rename a file in R, you can make use of the file.rename() function. The syntax of this function is as follows:

main.r
file.rename(from, to)
22 chars
2 lines

Here, from is the current name of the file and to is the desired new name of the file. These file names should include the path and the file extension.

Here's an example code snippet that demonstrates how to use the file.rename() function:

main.r
# Current name of the file
current_file_name <- "path/to/current/filename.txt"

# Desired new name of the file
new_file_name <- "path/to/new/filename.txt"

# Rename the file
file.rename(current_file_name, new_file_name)
220 chars
9 lines

This will rename the file from current_file_name to new_file_name. Make sure that the path is correct and that the user has write permissions to the directory where the file is located.
