plot(svm.auc, col=2, main="ROC curves comparing classification performance\n
of six machine learning models")
legend(0.5, 0.6, c(ns, nb, nr, nt, nl,ne), 2:6, 9) # Draw a legend.
plot(bo.auc, col=3, add=T) # add=TRUE draws on the existing chart
plot(rf.auc, col=4, add=T)
plot(tree.auc, col=5, add=T)
plot(nn.auc, col=6, add=T)
plot(en.auc, col=9,lty="dotted",lwd=3, add=T)
Hi, Dear community,
I am use the above codes to draw plot, but find that col =9 is not used by
the R. Instead, it use the col=2 when plot en.auc. WHy this happens and how
to check the col allocation in R?
Thanks!
