Hi, Pascal, I tried to use your method which functions but the values of the abscissa are not good. When I talked about “value”, I wanted mean the values of my starting dataset that I have classified into two classes positive and negative classes, such as this :
Value Status TPF TNF 1000 1 487 0 852 1 927 1 799 1 369 0 … … And for each value of my dataset, I want the tpf and tnf. With your method, I have an abscissa which has values between 0 and 1. All the best, Camille ----- -- Camille Leclerc, Master student Lab ESE, UMR CNRS 8079 Univ Paris-Sud Bat 362 F-91405 Orsay Cedex FRANCE -- View this message in context: http://r.789695.n4.nabble.com/ROC-Analysis-tp4469203p4471300.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.
