Question: Remove Column and Row from Matrix


I have a pretty simple problem and I feel pretty dumb just asking this. 
If I have a 2x2 Matrix and I remove one column and one row, how do I get the result to be a scalar, not 0th vector?

R := RandomMatrix(2);
R1 := DeleteRow(R,-1);
R2 := DeleteColumn(R1,-1);

                         R := [ -82  41 ]
                                  [-70  91]
                        R1 := [-82  41]
                          R2 := [-82]
