Sorry, there was one bit of legacy code in there (didn't
affect the error messages). Here's better:
#!/usr/bin/env python2.6
import rpy2.robjects as ro
df = ro.DataFrame({'a': ro.IntVector((1,2,3)), 'b': ro.IntVector((4,5,6))})
print df
print df.colnames
print df.rx2('a')
print [x for x in df.rx2('Date')]
for k,v in df.rx2('a').iteritems():
print k,v
JDO
