I'm less concerned with figuring out how to handle them in R than
figuring out how to get them into R via rpy2. DateVector would be
a nice way to handle this; how would you recommend doing it?
What I thought I might try is sending it in ISO format using datetime's
isoformat() operator, encapsulating that as a StrVector. This doesn't
work though:
sdpf = ro.DataFrame( {'rawdate': ro.StrVector([d.isoformat() for d in
rawdates]),

Subject: Re: [Rpy] python dates -> rpy dates -> ggplot2 dates, how to?
Date vectors in R can be handled in several ways. Check the
documentation and the R lists.
Having a DateVector is an interesting idea. It could possibly make
working with dates vectors easier from rpy2 than from R.
