Cannot use name 'pop' in Pandas DataFrame

[ijlyttle]

This may be related to #157

library("reticulate")

py_run_string("import pandas as pd")
py_run_string("df_bad = pd.DataFrame({'pop': ['foo']})")
py_run_string("df_good = pd.DataFrame({'apop': ['foo']})")

So far so good, but when I try to bring this into R:

py$df_bad

Error in py_get_attr_impl(x, name, silent) : 
  AttributeError: 'function' object has no attribute 'as_matrix'

However:

py$df_good

  apop
1  foo

It seems like the name 'pop' is somehow messing things up, and I don't think it should.

In python, doing

df_bad.pop.as_matrix()

gives an error. This is because pop is a method of a DataFrame.

The following in python works:

df_bad[['pop']].as_matrix()

It seems like somewhere in reticulate's conversion df_bad.pop.as_matrix is getting called and if that could be avoided by calling df_bad[['pop']].as_matrix that would solve the issue... there are likely other DataFrame methods other than pop that will lead to this kind of unexpected error.

Nice catch, thanks!

Assuming we can now close this?

Yes, thanks!
