[R] data set size question

Hi there,

I'm very new to R and am only in the beginning stages of investigating it for possible use. A document by John Maindonald at the r-project website entitled "Using R for Data Analysis and Graphics: Introduction, Code and Commentary" contains the following paragraph, "The R system may struggle to handle very large data sets. Depending on available computer memory, the processing of a data set containing one hundred thousand observations and perhaps twenty variables may press the limits of what R can easily handle". This document was written in 2004.

My questions are:

Is this still the case? If so, has anyone come up with creative solutions to mitigate these limitations? If you work with large data sets in R, what have your experiences been?

>From what I've seen so far, R seems to have enormous potential and
capabilities. I routinely work with data sets of several hundred thousand to several million. It would be unfortunate if such potential and capabilities were not realized because of (effective) data set size limitations.

Please tell me it ain't so.

Thanks for any help or suggestions.

Carl
