R help - May 2006 - how to plot additional function into pairwise scatterplots?

Hello,

I am new to R and want to use it for some statistical tests. Before the 
tests, I want to visualize my data with pairwise scatterplots using 
"pairs(myData)". To analyse it by eye, I would like to draw the
function
f(x)=y into each of the scatterplot panels. Unfortunately I get lost 
when I try to figure it out by reading "help(pairs)".

Can anyone help me or point me to a nice tutorial about graphics?

Regards,
Harald

Harald,
for your specific problem (add main diagonal) for example:
>  abline.points <- function (x,y,...) { points(x, y, ...); abline(0,1) }
>  pairs(USJudgeRatings[1:5], panel = abline.points, cex = 1.5 )
example(pairs)  has nicer examples.

Regards
Michael
