Dear Professor Cottrell, Currently all options for the xtab command are not available from the GUI at View > Cross tabulation. Specifically, the options --row (display row percentages), --column (display column percentages), and --zeros (display zero entries) are not accessible from the GUI. Could you please make these options available from the GUI too? Also, if it is not too hard, could you please add an option to save the cross tabulation table that is produced by the xtab command as a matrix? Thirdly, if it is not too hard and does not take too much time to implement, could you please add that Fisher's exact test is calculated and displayed as default for 2x2 contingency tables, together with the usual Pearson's chi-square test? Many thanks in advance. Best regards and thanks for a great software, Andreas Karlsson
