[R] How to make R automatic?
Hello, I have a question about how R can run automatically. Here is the story: A file called data.csv will be generated every couple of minutes in a folder (overwrite itself). What I want R to do is: 1) scan the folder to find the file. 2) if the file is a newly generated file, process the file 3) output some file identifier on the screen, such as the time when the file was generated. 4) pause for 20 seconds (doesnt need to be precise) and repeat 1) Idealy, I would like R to do this everyday from 9:00am to 6:00pm. What I got so far is: I can use list.files() and file.info to get 1) and 2). For 4), I can write some trivial loop to kill some time, but I would like to be more accurate tham that, considering different PC running the loop. I have no idea about 3). Any suggestion/better solution? Thank you very much!!
