Trying to import a bunch of data files named like f001, f002, ....f999. Some of the files may be missing and the missing files vary from time to time.
Used for loop and read.table. When it reaches the missing file (say f100), it shows: Error in file(file, "r") : cannot open the connection In addition: Warning message: In file(file, "r") : cannot open file 'f100': No such file or directory and the program stops. How can I skip the missing ones and keep the program running? Guess either checking the validity of filenames, or ignore the error message may work. Which functions should be used or any better ideas? -RJ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
