Using feature hashing/hashing tricks for machine learning in R

I just learned about feature hashing (also known as the hashing trick) and that some see it as an important feature for efficiently doing machine learning on large data sets.

However, I haven't seen anything like this being used for machine learning with R.

A Google search revealed that there is indeed a package hash on CRAN.

Could someone provide an example where this is used in R to speed up a machine learning task (or just to reduce RAM usage)?

I submit a package named FeatureHashing recently. Please check the github page for demo: https://github.com/wush978/FeatureHashing and let me know if you have any issue of using it.
