Is there any way suppress box color and frame of a box drawn by legend(,fill)? I am able to suppress the color, but not the frame (see the example below). Many thanks! (This follows up from a question asked on the list in 2006 by Florian Koller)
Tom x1 <- rnorm(100) x2 <- rnorm(100, 2) hist(x1, main = "", col = "orange",ylab = "density", xlab = "x", freq = F, density = 55,xlim = c(-2, 5), ylim = c(0, 0.5)) par(new = T) hist(x2, main = "", col = "green", ylab = "", xlab = "",axes = F, xlim = c(-2, 5), ylim = c(0, 0.5), density = 45, freq = F) abline(v = mean(x1), col = "orange", lty = 2, lwd = 2.5) abline(v = mean(x2), col = "green", lty = 2, lwd = 2.5) legend(3, 0.45, legend = c("x1", "x2", "mean(x1)", "mean(x2)"), col = c("orange", "green"), fill=c("orange","green", 0, 0), lty = c(0, 0, 2, 2), merge = T) ______________________________________________ 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.
