http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/*checkout*/pkg/NEWS?rev=487&root=zoo You can either wait for that, use the workaround you found or source the fixed version of plot.zoo: source("http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/*checkout*/pkg/R/plot.zoo.R?rev=472&root=zoo") On Wed, Jul 9, 2008 at 9:37 AM, stephen sefick <[EMAIL PROTECTED]> wrote: > n <- > c("f","m","a","m","j","j","a","s","o","n","d","j","f","m","a","m","j","j","a","s","o","n","d","j") > plot(x.zoo[, 95], xaxt = "n", ylim=c(1,2)) > rng <- range(time(x.zoo)) > axis(1, at = seq(rng[1], rng[2], 1/12), labels = n, tcl = -0.3) > > #why do I have to put in the y-lim explicitly?
