Read files in a folder when new data files come
Thank you for your reply, Yes, this is what I want to do. I am working on Windows. The data files is located in a folder on a data server. Each time the data collectors put the new data on the data server once they get new data. What I want to do is my R program will process those new data files once my program finds there are new data coming into that folder in this data server. Thanks, jlm

You can read the status of every file in a directory and make the decision to process it. ?One technique is to create a file in the directory the last time that you processed information from the directory. ?You could schedule an R script to first read in your 'flag' file and determine the date it was created and then get all the files in the directory that are later than that date to process them. You would then rewrite your flag file to update its modification date for the next round. Does this do what you want? On Sun, Jan 24, 2010 at 3:05 PM, jlfmssm <jlfmssm at gmail.com> wrote:
Hello, I am working on a project. The new data files is coming as the data collectors get data, then the data collectors put these new data files in a folder. I need to read these new data files when they are in folder. so far, I did this job manually, that is to say, each time I go to that folder and find new data files, then use my R program to read these new data files. I am wondering if anyone know how to perform this job automatically in R. thanks, jlm
