i'm plotting time-series and label the x-axis as follows: r <- as.POSIXct(round(range(p1$time), "month"))
plot(p1$time,p1$ p1, type="l", xaxt="n") axis.POSIXct(1, at=seq(r[1], r[2], by="month"), format="%Y.%m") what I want do do now, is a second label for the x-axis, that stands lower and indicates the years. I don't know how to proceed with all the possibilities in axis, par and plot thanks for your help ______________________________________________ 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.
