R as a lot more libraries, that cover specific needs, but the basics (and more) are all covered in Python, and are extremely easy to use.
You need: Python + Numpy (or Scipy) + statsmodels + Panda.
Or get a pre-packaged distribution that has all that, like Anaconda or Enthougt (haven't used them).
As for your question, you need Pandas, which is similar to R's data tables: http://pandas.pydata.org/
import pandas as pd
df = pd.read_csv('foo.csv', header=, sep=',')
