plotting several ROC curves on the same graph
...ot;,round(logit.roc.area(r),4)), pos=4)
title(main = title)
}
r[5,]=c(0,0,1,10)
logit.roc.plot(r)
r=r[-5,]
text(1 - max(r$spec,na.rm=T),
r$sens[which.max(r$spec)],r$pts[which.max(r$spec)],pos=2,cex=0.8)
while r is a MATRIX (4x4) with
colnames=c("pts",sens","spec",iterationnumber.")
and I have for each ROC curve a different matrix but all matrices have the
same
size. (They are organized as a list of 10 matrices by the size 4X4 each)
Would appreciate your help in putting all ROC curves on the same plot.
Thank you
