open file in r

To open a file in R, you can use the file() function. Here's an example:

main.r
# Open a file in read mode
my_file <- file("path/to/file.txt", "r")

# Do something with the file

# Close the file
close(my_file)
131 chars
8 lines

The first argument to the file() function is the path to the file you want to open. The second argument is the mode you want to open the file in. "r" stands for read mode. Other modes include "w" for write mode and "a" for append mode.

Once you're done working with the file, make sure to close it using the close() function. This will free up any system resources that were used by the file.
