panel.cor: panel.cor is a version of a function given in the help for pairs

Description

panel.cor is a panel function modified from that described in the help file for the pairs function from the graphics package. This has been customized both to show that one can make such customizations, and to enable this one to be used to calculate the correlations between the variables included in a pairs plot.

Usage

panel.cor(x, y, digits = 3, ...)

Arguments

x

the first variable - provided by pairs

y

the second variable, provided by pairs, see examples

digits

how many digits to use on the pairs plot for the correlations

...

any other graphics parameters to be passed to pairs.

Value

this prints the correlations in a square of the pairs plot

Examples

# NOT RUN {
  dat <- matrix(rnorm(900,mean=5,sd=0.5),nrow=300,ncol=3)
  pairs(dat[,1:3],lower.panel=panel.smooth,  # all should be
        upper.panel=panel.cor,gap=0.25,lwd=2) #low correlations
# }
