Re: [R] Problems with boxplot in ggplot2:qplot
Hi Dimitri, Have you looked at the examples for scale_x_date - http://had.co.nz/ggplot2/scale_date.html? They show you how to both set the limits and control the labels.

Re: [R] Problems with boxplot in ggplot2:qplot
Thank you, Hadley. I try
jpeg(file, width = 800, height = 600, quality = 100)
qplot(factor(closed$close.month), closed$closing.balance, geom = boxplot,
main = Monthly distributions of closing balances, xlab = Month,
ylab = Balance, USD) + theme_bw() + scale_x_date(major = months, minor
= weeks, format = %b)
dev.off()
('minor = ' can be skipped with no consequences, apparently). Labels
disappear altogether.

Re: [R] Problems with boxplot in ggplot2:qplot
Hi, it's hard to tell what's wrong without a reproducible example, but I noted two things: - AFAIK there is no plot method for ggplot2. You probably meant print(p) instead - if you map x to factor(month), I think it will be incompatible with your xlim values range(month).

Re: [R] Problems with boxplot in ggplot2:qplot
My bad: once I ran dev.off(), I did get a plot, albeit a blank one. Then I removed xlim - which I put in after qplot's complain about xlim - and voila!
