I have an RDa file that I created in R. I want to read this file on python as a pandas dataframe. I have the following code to do the same: import rpy2.robjects as robjects import numpy as np from rpy2.robjects import pandas2ri pandas2ri.activate() # load your file robjects.r['load']('Data.RDa') matrix = robjects.r['data'] matrix I get the following results: R object with classes: ('data.frame',) mapped to: <DataFrame - Python:0x0CF46F58 / R:0x0ED0F200> [Float..., Float..., Float..., ..., Float..., Float..., Float...] area: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0CF56A80 / R:0x0F281898> [NA_real_, NA_real_, NA_real_, ..., NA_real_, NA_real_, NA_real_] i: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0CF68E68 / R:0x0F2B9520> [NA_real_, NA_real_, NA_real_, ..., NA_real_, NA_real_, NA_real_] s: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0CF68940 / R:0x0F380008> [NA_real_, NA_real_, NA_real_, ..., NA_real_, NA_real_, NA_real_] ... upslope_area: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0D03FDA0 / R:0x0FE87C90> [NA_real_, NA_real_, NA_real_, ..., 292.256494, NA_real_, NA_real_] i: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0D03FC88 / R:0x0FEBF918> [331347.500000, 331352.500000, 331357.500000, ..., 332187.500000, 332192.500000, 332197.500000] s: <class 'rpy2.robjects.vectors.FloatVector'> R object with classes: ('numeric',) mapped to: <FloatVector - Python:0x0D03FE68 / R:0x0FEF75A0> [4554812.500000, 4554812.500000, 4554812.500000, ..., 4553982.500000, 4553982.500000, 4553982.500000] How do I convert this to a pandas data frame?
