组合两个二维阵列以产生三维阵列

Question

考虑数组SELECT * FROM foo1, foo2, foo3, foo4, foo5 WHERE ( foo1.id OR foo2.id OR foo3.id OR foo4.id OR foo5.id ) = ? 和x

y

如何将它们组合起来生成x <- structure(1:4, .Dim = c(2L, 2L), .Dimnames = structure(list(A = c("a", "b"), B = c("c", "d")), .Names = c("A", "B"))) y <- structure(5:8, .Dim = c(2L, 2L), .Dimnames = structure(list(A = c("a", "b"), B = c("c", "d")), .Names = c("A", "B"))) > x B A c d a 1 3 b 2 4 > y B A c d a 5 7 b 6 8 ：

z

这看起来是一个相当常见的操作，但我还没有找到一个功能 这样做。
