ggplot2 and Date class
...Sys.Date(), len=100, by="1 day")[sample(100, 50)], price = runif(50) )
> dt <- qplot(date, price, data=df, geom="line") + opts(aspect.ratio = 1/4)
> dt + scale_x_date()
Error in aesdefaults(data, .$geom$default_aes(), compact(.$mapping)) :
could not find function "as_df"
My ggplot2 package is up to date. Am I missing something else, maybe
in my default aesthetics?
Thanks,
