R help - Jun 2009 - color in pairs

Dear list

Is there any way that I can color the background (not the plotted points) of
each box in "pairs" ?

I'd like to color them according to the correlation coefficiency of
each data pair.

thanks.


N

Try this:

panel.cor <- function(x, y, ...)
{
     r <- abs(cor(x, y))
     u <- par('usr')
     names(u) <- c("xleft", "xright",
"ybottom", "ytop")
     bgcolor <- ifelse(r > 0.5, 'red', 'blue')
     do.call(rect, c(col = bgcolor, as.list(u)))
     points(x, y)
}

pairs(USJudgeRatings, panel=panel.cor)
