[R] SJava convert problem

[Spencer Graves]

      I have not previous knowledge of SJava, but I just went to 
www.r-project.org -> CRAN -> (selected a local mirror) -> "Software:  
Packages", and did not find SJava on the list.  Conclusion:  It's not a 
current R package.  I then went back to www.r-project -> search -> "R 
site search" -> SJava, and got 401 matches.  If you've already looked 
through them, then I apologize for wasting your time. 

      hope this helps.
