In case you have a dataset too big for fitting in memory for R, there is a package called biglm .
You install it like this-
install.packages("biglm", dep=TRUE)

bigglm                  Bounded memory linear regression     
biglm                   Bounded memory linear regression      
predict.bigglm          Predictions from a biglm/bigglm
and in case you are the statistical kind of chap who want to know what’s IN the code for these functions
function (formula, data, family = gaussian(), …)      
UseMethod("bigglm", data)      
<environment: namespace:biglm>
 
R tip of the day – If you want to know what an R Function say procmeans does…..all you need to do is type procmeans at the command prompt , and it will tell you what is inside the code.
If it gives an error most probably you need to
1) Install
and 2) Load the package containing the function
Which are conveniently here
