Hi you are correct as usually. It is about 10 versions 1.2.0 - 2.2.1 and as there are 2 versions per year it is about 4-5 years.
[That calculus only goes back to 2001, though, previous to that the release rate was higher (and the numbering stranger). And it is of course a coincidence that 2.0.0 followed 1.9.x.]
But nevertheless it seems to me as if I used R forever (and hopefully it will continue) Anyway subsetting data frames **was** similar in the old versions as it is now, wasn't it?
Yes, AFAIR, and just tested in 1.2.2.
AFAIR, the current data frame code was adopted in late 1997 from the code that John Chambers had donated to Statlib...
