I apologize if the term "submatrix" was confusing - I am basically 2 rows and 2 columns from a r x c matrix to construct 2x2 matricies. Thus, the choose(r,2) * choose(c,2) possible combinations. For each matrix [(a,b), (c,d)],
What does that mean? -- it ain't R syntax. Is (a,b) a row or column? Also, please don't post through Nabble, as R-help is a separate mailing list and we lose context here (and don't wish to mess with Nabble). -- Bert -- Bert I am testing a > b, b > d, d > c, and c > a.
For the sake of simplicity I have combined these tests into a single function (with the intent of applying it to the matrix, ideally). I hope this is clearer... -- View this message in context: http://r.789695.n4.nabble.com/Help-with-applying-a-function-to-all-possible-2x2-submatrices-tp4647048p4647065.html Sent from the R help mailing list archive at Nabble.com.
