Dear all, how can I "reshape"/"cast" the following matrix
00;01;10;11 John.Mike;123;313;12;31 John.Jim;54;57;39;36 John.Steve;135;47;47;74 Mike.Jim;63;37;27;16 Mike.Steve;15;15;5;61 Jim.Steve;6;10;34;35 into a set of stacked 2x2 contingency tables 0;1 John;123;12 Mike;313;31 John;54;39 Jim;57;36 John;135;47 Steve;47;16 ... so that the "fisher.test" and "chisq.test" can be "applied" to the pairs of names. As as result I would like to have the original format, ie John.Mike John.Jim John.Steve Mike.Jim Mike.Steve Jim.Steve with two columns containing the p-values of the tests.
