Regression for data too large to fit in memory. This package functions exactly like the 'biglm' package, but works with later versions of R.
This is basically Alan Miller's modification (AS274) of the other Gentleman's (AS 75) regression by incremental QR decomposition. It has been lifted out of the "leaps" package and wrapped with an lm-like interface to make experimentation easier. The calculation of the sandwich covariance estimator in the same single pass over the data is new.
