java - Error message I do not understand R renjin -

-

i asked solution before, apparently not helped renjin rather experimental still...but maybe please translate error message plain english?

maybe can determine if can reasonable hope solve problem in reasonable time or if should rather abandon renjin.

here message:

exception in thread "awt-eventqueue-0" org.renjin.eval.evalexception: object 'c_hclust'    not found

here code:

private void cluster()  {     try {         this.engine.eval("dis<-dist(mymatrix, \"binary\")");     } catch (scriptexception ex) {system.out.println(1);         logger.getlogger(rworker.class.getname()).log(level.severe, null, ex);     }      try {         this.engine.eval("clus<-hclust(dis)");     } catch (scriptexception ex) {system.out.println(3);         logger.getlogger(rworker.class.getname()).log(level.severe, null, ex);     }     try {         this.engine.eval("plot(clus)");     } catch (scriptexception ex) {system.out.println(4);         logger.getlogger(rworker.class.getname()).log(level.severe, null, ex);     } }

i did not of prints, however.

c_hclust function stats package written in c not yet included in renjin. integrating c/fortran code gnu r stats package test , expand our c/fortran translator.

we're looking contributors might mini project if want involved - can take stab @ copying relevant sources int packages/stats/src/main/c , see if compiles out error.

otherwise completing functionality of stats package priority , can in near future!
