I converted a pandas dataframe to R using the code below:
import pandas as pd
import pandas.rpy.common as com
import rpy2.robjects as ro
from rpy2.robjects.packages import importr
rdf = com.convert_to_r_dataframe(df)
How do I convert rdf back to a pandas.DataFrame?
df = f(rdf)
Use pandas to read an rpy2 dataframe, r_df. It will avoid the deprecation warning "FutureWarning: from_items is deprecated. Use DataFrame.from_dict(dict(items), ...) instead"
type(r_df) is "rpy2.robjects.vectors.DataFrame".
type(pd_df) is "pandas.core.frame.DataFrame"
pd_df = pd.DataFrame.from_dict({ key : np.asarray(r_df.rx2(key)) for key in r_df.names })
