Hi Carson,
The following code worked to me:
import rpy2.robjects as ro
d_str = dict(x = ro.StrVector(["abc", "def", "ghi"]), y =
ro.StrVector(["yes", "no", "maybe"]))
dataf_str = ro.r['data.frame'](**d_str)
print dataf_str
Cheers

Hi list,
I'm wondering if anyone can tell me how to convert a dictionary of lists
of strings, into an R data.frame using rpy2. I've seen lots of talk
about converting lists of numeric values to data.frames using arrays,
but I can't seem to get anything to work for strings.
For example, the fol

Actually, I hadn't. But trying it gave me the same "raveled" result:
>>> len(dl)
12
>>> map(len,dl)
[306, 306, 306, 306, 306, 306, 306, 306, 306, 306, 306, 306]
>>> x=ro.r['data.frame'](dl)
>>> len(x)
3672
>>>
