Hi there, Here is the panel.cor function from ?pairs:
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) } in the following code, pairs use the panel.cor defined above: pairs(USJudgeRatings, lower.panel = panel.smooth, upper.panel = panel.cor, gap=0, row1attop=FALSE) I try to change prefix = "" to prefix = "r = ", something like: pairs(USJudgeRatings, lower.panel = panel.smooth, upper.panel = panel.cor, prefix = "r = ", gap=0, row1attop=FALSE) I got lots of warnings. How to change prefix to something else, but not change the defined panel.cor? Thanks!
