How to use file_test() In R Language

This function can also be used to check whether the file is existing or not.

Syntax: file_test(op, x, y)

Parameter:

• op: a character string specifying the test to be performed. Unary tests (only x is used) are “-f” (existence and not being a directory), “-d” (existence and directory) and “-x” (executable as a file or searchable as a directory). Binary tests are “-nt” (strictly newer than, using the modification dates) and “-ot” (strictly older than): in both cases the test is false unless both files exist.
• x, y: character vectors giving file paths.

Returns: The function file_test() returns a logical vector indicating whether the files named by its argument exist.

• TRUE- file exists
• FALSE- file does not  exists
