“R has been traditionally limited by the need to fit data sets into memory, and working with even modest sets of data can quickly exhaust memory due to historical limitations in GNU R interpreter’s implementation.”

I see that the propaganda machine never rests, no matter which language. Either that, or they haven’t heard of Vertica’s R, which is excellent and counters these claims.

The rest with the “fragmentation of R” is a poor marketing tack: people who run R are perfectly capable of thinking with their own brains, thank you very much; Renjin has no place patronizing. We’re not sheep.
