Dear R-users, I would like to add a legend at the bottom of pairs plots (it's my first use of this function). With the plot function, I usually add some additional space at the bottom when I define the size of the graphical device (using mar); grid functions then allows me to draw my legend as I want. Unfortunatley, this technique does not seem to work with the pairs function as the generated plots use all the available space on the device (see below). I guess I am missing a key argument... my attempts to modify the oma, mar, usr arguments were unsuccesfull, and I could not find any helpful threads on the archives.
As usual, any advice would be greatly appreciated Sebastien pdf(file="C:/test.pdf", width=6, height= 6 + 0.2*6) par(mar=c(5 + 6,4,4,2)+0.1) pairs(iris[1:4], main = "Anderson's Iris Data -- 3 species", pch = 21, bg = c("red", "green3", "blue")[unclass(iris$Species)]) dev.off() ______________________________________________ R-help@stat.math.ethz.ch 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.
