Did you run the panel.cor?
pairs(z,upper.panel=panel.cor)
Error in pairs.default(z, upper.panel = panel.cor) :
? object 'panel.cor' not found
panel.cor <- function(x, y, digits = 2, prefix = "", cex.cor, ...)
????? {
????????? usr <- par("usr"); on.exit(par(usr))
????????? par(usr = c(0, 1, 0, 1))
????????? r <- abs(cor(x, y))
????????? 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 = cex.cor * r)
????? }
? pairs(z,upper.panel=panel.cor)
