R help - Mar 2010 - how to plot only the upper triangle using the pairs function?

Hi,

I am trying to use function pairs to plot the scatterplot, but I only want
to keep the upper triangle, what's the argument to do this?

Thanks,

-Jack

Try setting the 'lower.panel' argument to NULL.

Compare:

  pairs(USJudgeRatings)

to:

  pairs(USJudgeRatings, lower.panel = NULL)

I don't really understand what you're trying to ask, but does
upper.tri function help?

R> ?upper.tri

Is this what you want?

Also look at the pairs2 function in the TeachingDemos package for a way to plot
one set of variables against another set.
