ROCR Issue: Averaging Across Multiple Classifier Runs in ROC Curve
...vowel.ROC <- list(predictions=list(), labels=list())
For every run of the classifier, I append the scores and labels to
their corresponding list elements as follows:
vowel.ROC$predictions <- append(vowel.ROC$predictions,
list(scores))
vowel.ROC$labels <- append(vowel.ROC$labels, list(numGrps))
The R display of vowel.ROC looks like the following (not sure why NULL
is there):
List of 2
$ predictions:List of 4

..$ : num [1:152] 0.99 0.974 0.934 0.767 0.934 ...
