Error when trying to create choropleth map using R's choroplethr package

[pybokeh]

Here's my traceback:

Traceback (most recent call last):

    key = min(all_data.keys(), key=lambda k: order[k])
ValueError: min() arg is an empty sequence  

My markdown file just contains:

```{ir}
library(choroplethr)
data(df_pop_state)

state_choropleth(df_pop_state, 
             title  = "2012 State Population Estimates",
             legend = "Population")

**EDIT:** forgot to add that the R code works fine in jupyter notebook.  I think perhaps the map that gets generated is too big?

Thanks for the report. Should be fixed in 2c8a3a7 if you want to give that a shot. Apparently some R output returns empty messages. In python these go over stdout.

@TomAugspurger That worked. Thanks Tom!
