Sure, there are several approaches to this, but in general thinking about your data in terms of 'grouping' factors can be helpful example: # 1 year's worth of dates: d <- strptime(1:365, format="%j") # some simulated data x <- rlnorm(365) # combine them into a DF dx <- data.frame(date=d, value=x) # plot the data, note that x-axis is in dates: plot(dx) # now generate a grouping factor. how about months: dx$month <- format(dx$date, format="%B") # box and whisker plot for data *grouped* by month boxplot(value ~ month, data=dx, las=3) cheers, Dylan ______________________________________________ R-help@r-project.org 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.
