Changbin -
Please take a look at the help file for the function
"palette", which is how R maps col= numbers to colors.
Also look at the default output of that function:
palette()
[1] "black" "red" "green3" "blue" "cyan" "magenta" "yellow"
[8] "gray"
You might get better results by specifying the colors that you
want directly.

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!
