The function prediction() returns this: Formal class 'performance' [package "ROCR"] with 6 slots ..@ x.name : chr "Cutoff" ..@ y.name : chr "Accuracy" ..@ alpha.name : chr "none" ..@ x.values :List of 1 .. ..$ : Named num [1:89933] Inf 2.23 2.22 2.17 2.16 ... .. .. ..- attr(*, "names")= chr [1:89933] "" "36477" "56800" "41667" ... ..@ y.values :List of 1 .. ..$ : num [1:89933] 0.5 0.5 0.5 0.5 0.5 ... ..@ alpha.values: list()
Now, since I want to match each prediction with its original case, I need to extract the names, i.e. the information in "- attr(*, "names")= chr [1:89933] "" "36477" "56800" "41667" ..." so I can use it with a simple datafile[names,] query. How do I get these names in plain number formats? ______________________________________________ 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.
