What these "labels" you are referring to? > All the data is in floats. > > Can anyone give me some short examples to open my file? The default settings for `read.table` assume that there is no header row and that `NA` is the missing value indicator. See ?read.table for more on the default settings. If you have `NaN` as missing value you need to include an na.strings="NaN" argument in the `read.table` call. You would need to post process results to exclude rows. There is no interval skipping mechanism that I know about. `scan` assumes all lines have the same structure so answering the question about "labels" would be necessary for any advice about its use here. > > Look forward for your support, > > Thanking you in advance, > Regards, > Madhavan > [[alternative HTML version deleted]] I suggest you investigate how to configure your mail-client to respond in plain text. > > ______________________________________________ > [email protected] mailing list -- To UNSUBSCRIBE and more, see > 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.
