plot(x, color="blue", type="l", bty="n", 
     xlab="False positive rate", ylab="True positive rate", 
     main="ROC curve", ...)

## S3 method for class 'Daim.list'
plot(x, color=rgb(1,0,0,alpha=0.5),
     lty=1, lwd=1, pch=19, 
     xlab="False positive rate", ylab="True positive rate", 
     main="ROC curves", legend=TRUE, ...)
