How to do it…

The steps to building a linear regression model using the rxFastLinear() function from the RevoScaleR library are as follows:

1. Connect the XDF file with the R session by creating an object in R.
2. Load the RevoScaleR library.
3. Specify the outcome and feature columns into the formula and parse through the rxFastLinear() function.

Here's the exact R code to implement the preceding steps:

        setwd("D:/AllSync/Drive/Book-3/codeBundle/ch9")        xdfFile <- file.path(getwd(), "USAirlines2016.xdf")        linMod <- rxFastLinear(ARR_DELAY~DEP_DELAY+ORIGIN+DEST+DAY_OF_WEEK,         type = "regression", data = xdfFile)
