Oh, yes, I was aware that R (and its predecessor S) have a native dataframe object in the language.

It seemed that gmfawcett was indicating that there was a dataframe library in _Python_ that existed prior to Pandas. I was curious what that library was/is, as I'd not heard that before.

ok, guess I misunderstood both comments of you two. ´_>`

Sorry :) Pandas is undisputed king. But there were multiple bindings from Python into R available in the early 2000's. Some like rpy and rpy2 are still around, others are long defunct. I concede that these weren't standalone dataframe libraries, but rather dataframe features built into a language binding.
