Hello Robert,

Congratulations on the book.

I have two questions.
1) How much of R and it's use in the Big Data field do you cover in your book?
2) Is R the best open source language for Big Data or are there alternatives which are more suited to this emerging field?

Kind Regards,

Kondwani.

Hi Kondwani,

It depends on your definition of BIG data. If you have data in the Gigabyte range (or have a larger dataset in a DMBS but only need to analyze a subset of it) then the methods in R in Action will work just fine. There is an Appendix on BiG Data (Terabyte range), but it is not the focus of the book. If you need to analyze REALLY large datasets (and not subsets of them), you can use special functions in R or turn to commercial version of R by Revolution Analytics or Oracle. Other language alternatives are Python and Julia.

Hope this help,

Rob
