How to do it…

The following are the steps for this recipe:

1. Create an object containing the filename and the location of the XDF file.
2. Load the RevoScaleR library.
3. Parse the XDF file through the rxDataSetp() function and perform the transformation.

Here's the R code corresponding to the preceding steps:

        xdfFile <- file.path(getwd(), "USAirlines2016.xdf")                   rxDataStep(inData = xdfFile,                   outFile = xdfFile,                   transforms = list(binDelay = ifelse(DEP_DELAY>0,1,0)),                   overwrite = TRUE)
