Sorry I forgot the "" around the dates x <- c(dates("01/31/03"),dates("06/30/07"))
But I think your problem is the plot area . You must first define the plot area with type ="n" for no plotting, afterwards you could fill in the data. I did this with times() but I am afraid the displayed dates/times will depend on your plot area and the settings with par() did you read the instructions for plot and par already? Regards Knut have a look to ?plot and to ?par ______________________________________________ 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.
