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@8813f2"
[[2]]
[1] "Java-Array-Object[D:[D@1d58aae"
[[3]]
[1] "Java-Array-Object[D:[D@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?
