Errors while using geom_subplot2d

[KMGehweiler]

There are several errors while using subplot2d:

ggplot(casualties, aes(lon, lat), size = 0) +geom_subplot2d(aes(lon, lat, subplot = geom_bar(aes(victim, ..count.., fill = victim))), ref = NULL, width = rel(0.8))
Using binwidth 1.36

I really like the idea of this package, but it makes me sad that the example for embedded bar charts isn't working. :-(

KMG,

Thanks for pointing this out. The first three examples work on my machine. I suspect it has to do with package versioning. Do they go away for you when you run R 2.15.1 and ggplot2 v 0.9.2?

The last example fails because of the way you use breaks. geom_subplot2d needs breaks to be a list that contains a vector for the x variable and a vector for the y variable. In this case, the ranges of lat and lon are fairly far from c(-1, 1). Try something like this. It should work.

ggplot(casualties, aes(lon, lat), size = 0) +
  geom_subplot2d(aes(lon, lat, 
    subplot = geom_bar(aes(victim, ..count.., fill = victim))), 
    breaks=list(c(60,65,70, 75), c(28, 33, 38)), ref = NULL, width = rel(0.8))

Thank you very much, everything works now! :-)
(I was working with R 2.15.0 before.)
