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 Thanks, Nestor -- Nestor Arguea Chair, Marketing and Economics Director of International Business Programs University of West Florida ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
