I am tring to create a plot with two y-axis. I found an example which is fine but the problem is that the range of the second y-axes appears in the first y-axes causing confusion. [...]
The key is the "ann = FALSE" in the second plot():
n = 100 x = rnorm(n) y = rnorm(n) z = rnorm(n) * 250
par(mar = c(5, 4, 4, 5) + 0.1) plot(x, y, ann = FALSE)
par(new = TRUE) plot(x, z, col = 'blue', axes = FALSE, ann = FALSE) axis(side = 4, col.axis = 'blue')
title(xlab = 'x', ylab = 'y')
mtext('z', side = 4, line = 3)______________________________________________ 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
