ordered label in ROCR# Biology - 生物学
G*G
1 楼
I don't understand how to order the label in ROCR package in order to
get the correct result. I am wondering whether you can help me.
library(ROCR)
data(ROCR.simple)
pred svm.auc plot(svm.auc)
#####label
ROCR.simple$labels[ROCR.simple$labels=="0"]="tumor"
ROCR.simple$labels[ROCR.simple$labels==1]="normal"
pred svm.auc plot(svm.auc)
The ROC curve is flipped. How do we know which order of labels we should
choose?
Is this a bug of ROC?
thank you very much.
