I added this R code to the bottom of the previous code and it doesn't work

> ar34Ret <- .jcall(qsLin,returnSig="[[D","arReturnTEST")
> print(ar34Ret,digits=20)

[[1]]
[1] "Java-Array-Object[D:[D_at_8813f2"

[[2]]
[1] "Java-Array-Object[D:[D_at_1d58aae"

[[3]]
[1] "Java-Array-Object[D:[D_at_83cc67"

> for(i in 1:3) for(j in 1:4) print(ar34Ret(i,j),digits=15)
Error in print(ar34Ret(i, j), digits = 15) :
  could not find function "ar34Ret"
>

The Java code is:
public final static double[][] arReturnTEST() {   double[][]retArr=new double[3][4]; for(int i=0;i<3;i++)for(int j=0;j<4;j++)retArr[i][j]=i*1000+j; return(retArr); }
R doesn't know how to print the array in the next to final line, and thinks the array is a function in the final line.

Any suggestions?
