Hi to all, I'm sorry for posting this question, I am sure I am missing something important but after reading the documentation I cannot find where the problem is.
I want to add a legend to a figure. If I use a simple example drawn from the R Reference Manual such as, for instance: x <- seq(-pi, pi, len = 65) plot(x, sin(x), type="l", col = 2) legend(x = -3, y = .9, "legend text", pch = 1, xjust = 0.5) then everything works just fine. However, if I use other data such as, for instance: y<-c(1960, 1965, 1970, 1975) z<-c(1, 2, 3, 4) plot(y, z, type="l", col = 2) legend(x = -3, y = .9, "legend text", pch = 1, xjust = 0.5) then the legend is not shown. Any hints? Thanks in advance, Emili ______________________________________________ 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.
