Thanks Michael. Also for the Github tip.

Base R's data.frame uses as.data.frame() to coerce its arguments, passing optional=TRUE. With optional=TRUE, vectors and other things without column names coerced to data.frames will have NULL names, so data.frame() can tell the difference between real/original names and concocted names, for which it uses the argument name or the deparsed argument as a last resort. Since DataFrame does not support NULL names, we have long relied on a heuristic that breaks in this case: > DataFrame(list(data.frame(foo=1))) list.data.frame.foo...1.. <numeric> 1 1 > data.frame(list(data.frame(foo=1))) foo 1 1 I will fix this somehow. Btw, you can submit these types of issues through github now.
