Hello,
Its doesn't look like the message posted by Peter Sudmant on April 21st
hasn't gotten a reply yet and I'm noticing the same problem with
creating a dataframe and plotting it with ggplot. With python 2.6.5,
rpy2 2.1.1 and R 2.11.0, I try the following from the documentation:
--
import rpy2.robjects.lib.ggplot2 as ggplot2
import rpy2.robjects as ro
d = {'a': ro.IntVector((1,2,3)), 'b': ro.IntVector((4,5,6))}
dataf = ro.DataFrame(d)
gp = ggplot2.ggplot(dataf)
pp = gp + ggplot2.geom_point()
pp.plot()
--
and get the following:
--
Error: attempt to apply non-function

I can type "print dataf" and the data frame prints fine. Also, loading
the "mtcars" dataframe example mentioned in the documentation works
fine. Any suggestions?
Thanks
Jeremy
