find the last modified date of a file in r

You can use the file.info() function in R to get the metadata of a file, including the last modified date. Here's an example code snippet:

main.r
# set the file path
file_path <- "path/to/your/file.txt"

# get the file info
file_info <- file.info(file_path)

# extract the last modified date
last_modified <- file_info[["mtime"]]

# print the last modified date
print(last_modified)

The file.info() function returns a named list of file metadata, where "mtime" represents the last modified date. The last_modified variable extracts this information and can be printed or used in further calculations as needed.
