Command pairs() does not show the correlation coefficient on the upper
diagonal of a set of scatter plots. The command produces an error in
Windows 7, but it works fine in OS X Mavericks with the same R version
3.0.2. Platform, R version and example under Windows 7 provided
below.
$platform
[1] "i386-w64-mingw32"
...
$version.string
[1] "R version 3.0.2 (2013-09-25)"
Example:
> set.seed(12345)
> x <- rnorm(10)
> y <- log(c(2:11))
> z <- data.frame(x,y)
> cor(z)
x y
x 1.0000000 -0.4867929
y -0.4867929 1.0000000
> pairs(z)
> pairs(z,upper.panel=panel.cor)
Error in pairs.default(z, upper.panel = panel.cor) :
object 'panel.cor' not found
