> table = r.table(wordsvector)

The table function returns a _contingency table_ object, which rpy
tries to unsuccessfully convert into a numpy array.

See if this returns something more workable:

rObj = with_mode(NO_CONVERSION, r.table)(words)
aHash = {}
[aHash.update(i) for i in rObj]
print aHash

> filecontent = r.tolower(filecontent)
> words = r.strsplit(filecontent, " ")

Also, you should probably use python to do this instead making the
trip through R:

filecontent = filecontent.lower()
words = filecontents.split(" ")
