Hi
I have 4 vectors x,y,z,v
I need 2 graphs (x~y,z~v) on the same plot. I mean two lines on the same plot - blue and red.
I wrote:
 
c.pl=xyplot(y~x,
          na.rm="TRUE",type="l",more=TRUE,
          scales = list(cex=3/4,x=list(tick.number=3,alternating = c(0,1)),y=list(tick.number=7)),   
          panel = function(x,y,...) {
          panel.grid(h=-1,v=3,lwd=1/8,col=COLAVG,lty=3)
          panel.xyplot(x,y,...)

        }
   
   )

How can I pu the second x~v graph on the same plot???
   
     
   

  print(c.pl)
