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.
