I'm practicing my Python, specifically my numpy and pandas. I have some data (not mine) in .rda format that I want to import into python as a dataframe. However I don't use R, so I'm wondering if I can do this without fiddling around with the base file. From what I've seen on the site, feather has been recommended and so I've tried the following:

import feather
path = 'pathtomydata.rda'
df = feather.read_dataframe(path)

But this produces a "ArrowInvalid: Not a feather file" error, which makes it sound like I have to dig into the .rda file and make it into a .fea file first, which I'd rather not do as I imagine I'd have to install R. Many thanks in advance.

You can use pyreadr, which does not require R to be installed:

import pyreadr

result = pyreadr.read_r('pathtomydata.rda')

# done! let's see what we got
print(result.keys()) # let's check what objects we got
df1 = result["df1"] # extract the pandas data frame for object df1
