[R] Problems with boxplot in ggplot2:qplot

[baptiste auguie]

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).

HTH,

baptiste
