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
