Good question pdb,
I would suggest you to use:
par(bg = "white")
In the beginning of the code,
But it doesn't solve the general problem of how to get the "lines" to be
properly aligned.
I am curious for the answer from betteR people.
Best,
Tal
Instead of screen(), why not use lattice with trellis.focus().
Have a look at the examples in ?trellis.focus.
Also, there are some examples in ?xyplot.zoo in the zoo package.

I am doing calculations in a loop and then plotting the results by adding a
point to each of 2 charts at the end of the loop. Its very informative as
you can see the progression through time.
My problem is, if I have 2 plots, I don't know how to get the focus back to
the first plot.
layout(matrix(c(1,2)))
plot(iris[,1],col="red",) #plot1
plot(iris[,3],col="blue") #plot2
#goes on plot2
lines(iris[,2],col="pink")
#how do I put this line on plot 1
lines(iris[,4],col="black")
I tried the method below but when you switch the focus back to screen 1 the
line gets drawn not where I expect
split.screen(c(2,1))
screen(1) # prepare screen 1 for output
plot(iris[,1],col="red",) #plot1
screen(2) # prepare screen 2 for output
plot(iris[,3],col="blue") #plot2
screen(1)
lines(iris[,2],col="pink",lwd=8)
screen(2)
lines(iris[,4],col="green",lwd=8)
Any pointers please as to what I need to do?
