Hello dear R Users, I am working on a dataset of 928 Enterprises, of which are observed 12 different characters. I need to randomly sample, without repetition, 70% of the entreprises, to create a testing set, and let the other 30% of the enterprises be a validating set (holdout validation, I think that is). How do I do that? Of course all the characters of each row must remain together. Also, I am not very familiar with the R-Base language (it is the first time I use it) so if You could also explain to me what every function and argument means, it would be great help to then reiterate the procedure.
Thank You very much, Sebastiano -- View this message in context: http://www.nabble.com/Extracting-random-rows-from-a-dataset-tp21530539p21530539.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
