Hi,
The class conversion example from section 4.3.2 of the manual
demonstrates how to apply a conversion function to dataframes. However,
I am having difficulty doing this for lists and vectors. In the example
below the function is applied to the dataframe, but not to the list.
The manual mentions that the class attribute of the obj is used. An R
list does not have a class attribute, however the class() function
returns 'list'. What class string should I use?
Thanks,
Michael
from rpy import *
set_default_mode(CLASS_CONVERSION)
def f(o):
#this function should be called for class conversion
return 'works!'
class_table['data.frame'] = f
class_table['list'] = f
r.as_data_frame([1,2,3])
>>> works!
r.list(c=[1,2,3], g=['w','r'])
>>> {'c': [1, 2, 3], 'g': ['w', 'r']}
r.class_(r.list(c=[1,2,3], g=['w','r']))
>>> list
