Thank you very much! I wasn't aware of the circumstance that mode(matrix()) of course returns 'logical'. Maybe one could warn the user in the function "edit(x)" that if (is.matrix(x) && is.logical(x) == TRUE) that edit(x) doesn't work since my workaround was that I created a matrix of the dimension 10x20 via matrix(NA, nrow=10, ncol=20) and used the GUI data editor to fill the matrix's cells with values.
