R help - Aug 2009 - problem plotting with ggplot2

Dear R-Help subsribers,

 upon running into a wonderful ggplot2 package by accident, I abruptly
encountered another problem. Almost every command run with ggplot2 results
in some sort of error. The one below is far the most common one. Kind people
from ggplot2 mailing list couldn't manage to solve the problem, so I'm
re-posting it here to try my luck. I will recommend myself for any tips on
how to solve this, as I would really benefit from using this package.

 > head(cebelice)
   time c2
1 00:00  0
2 00:15  0
3 00:30  0
4 00:45  0
5 01:00  0
6 01:15  0
> dim(cebelice)
[1] 96  2
> ggplot(cebelice, aes(x=time, y=c2)) + geom_histogram()
Error in all.vars(as.formula(.$facets)) :
  could not find function "as.formula"


This is straight from ggplot2 sample page for barplots:
> c <- ggplot(mtcars, aes(factor(cyl)))
> c + geom_bar()
Error in get("transform", env = ., inherits = TRUE)(., ...) :
  attempt to apply non-function


Sincerely yours,

Roman

Hi,

Have you checked that you have the latest version of ggplot2 and plyr?
Please post your sessionInfo()
