Implementing Java pattern mining algorithm into R

In essence, I need to take the available open source Java code and implement it into R so that I can call it and run it on several data sets in R Studio. The pattern mining algorithm that I am interested in is VMSP (“[login to view URL]”) and can be found on (look for [login to view URL]): [login to view URL] I am not sure whether the algorithm has to be translated, or whether it is possible to embed it into R.
