Rather than subsetting the x, I'd just use xlim and ylim arguments to plot() to change the range. For example, plot(ecdf(x), do.points=FALSE, verticals=TRUE, xlim=c(1, max(x)), ylim=c(1-sum(x>1)/length(x), 1)) Duncan Murdoch ______________________________________________ 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.
