I need help with RJava. So I run this R code:library(rJava) #load the rJava library .jinit(classpath="c:/Documents and Settings/GV/workspace/Test/src", parameters="-Xmx512m") #the above is to load the Java virtual machine, x = runif(1000) y = runif(1000) #the above are two vectors to convolve #now you can call the Java method as z=.jcall("Test", "[D", "convolve", x,y) I get an error Error in .jcall("Test", "[D", "convolve", x, y) : RcallMethod: cannot determine object class. Why is this?
It would be useful if you showed your Test java class and repost on the appropriate mailing list for rJava: http://mailman.rz.uni-augsburg.de/mailman/listinfo/stats-rosuda-devel
