Hi,
strangely, when I run this script:
panel.cor = function(x, y, digits=2, prefix="r=", cex.cor)
{
usr = par("usr"); on.exit(par(usr))
par(usr = c(0, 1, 0, 1))
r = abs(cor(x, y, use="pairwise.complete.obs", method = "pearson"))
txt = format(c(r, 0.123456789), digits=digits)[1]
txt = paste(prefix, txt, sep="")
if(missing(cex.cor)) cex.cor = 0.8/strwidth(txt)
text(0.5, 0.5, txt, cex = cex.cor)
}
pairs(cap[8:11], lower.panel=panel.lm, upper.panel=panel.cor, cex=2)
I get linear regression and density ellipse, why?
Is it possible to add also the data point?
Thanks a lot
