In the pairs help is an example how to plot the correlation as txt.
How do I get rid of the axes
in the upper panel?
regards
## put (absolute) correlations on the upper panels,
## with size proportional to the correlations.
panel.cor <- function(x, y, digits = 3, prefix = "",
cex.cor,axis=F, ...)
{
tt<-cbind(x,y)
idx<-apply(tt,1,function(x){sum(is.na(x))==0})
x<-x[idx]
y<-y[idx]
usr <- par("usr"); on.exit(par(usr))
par(usr = c(0, 1, 0, 1))
r <- abs(cor(x, y))
print(r)
txt <- format(c(r, 0.123456789), digits = digits)[1]
txt <- paste0(prefix, txt)
if(missing(cex.cor)) cex.cor <- 0.8/strwidth(txt)
text(0.5, 0.5, txt, cex = r^20*cex.cor)
}
