Hi there, I'm having some difficulty with the ROCR package. I've installed it fine, and the sample data works (ROCR.simple), however when I try to load my own data it complains that the number of predictions should be the same as the number of labels for each run. I imported as a txt file with two columns (one binary 0 and 1, and the other probabilities), and each column has the same number of rows (8934). I'm mystified as to why it is giving this error...
Thanks for any assistance -- View this message in context: http://r.789695.n4.nabble.com/ROCR-data-format-tp2328000p2328000.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.
