extract the latest entry of a file in r

To extract the latest entry of a file in R, you need to do the following steps:

1. Open the file using the file() function.
2. Read the contents of the file using readLines() function.
3. Manipulate the data to extract the latest entry.
4. Close the file.

Here is an example code snippet:

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

# Open the file
file_conn <- file(file_path, open = "r")

# Read the contents of the file
file_contents <- readLines(file_conn)

# Extract the latest entry
latest_entry <- tail(file_contents, n = 1)

# Close the file
close(file_conn)

15 lines

In this code, we first set the file path variable with the path to our desired file. We then open the file using the file() function and set the read mode as "r". Next, we read the contents of the file using readLines() function, which stores the contents of the file in file_contents variable. Finally, we extract the latest entry by using tail() function and access the last line of the file_contents variable.

After that, we close the file using the close() function to release the system resources used by the file. The resulting variable latest_entry will contain the latest entry of the file as a string.
