Color of ecdf plots

Hi.

 

I have the following two ecdf plots in one graph:

 

 plot(
  ecdf(....),
  do.points=FALSE,
  verticals=TRUE,
  main=paste("Ecdf of distances ",DIM,sep=""),
  col="red"
 );
 lines(
  ecdf(....),
  do.points=FALSE,
  verticals=TRUE
 );

 

How do I change the color of the resulting graph? Adding col="red" to either plot or lines results in an error ...

 

Thanks!

Lars
