Hi, all, I am a newbie for [R] Would anyone help me how to transpose a 3x3x3 array for 1:27 Eg. A<-array(1:27, c(3,3,3) What is the logic to transpose it to B<-aperm(A, c(3,2,1)) Because I found I could not imagine how it transposes, anyone could solve my problem? And most important I could get the number what I expected, I think if I could not figure it out, I will have a confused concept which will affect my future learning of 3D models in [R]. Highly appreciated and thanks.

It simply says third dimension first, second second, and first third. Uwe Ligges

Mr. Disease, As Uwe points out, the syntax is pretty clear, but it is perhaps worth mulling over why: R> identical(A[,,1], t(B[1,,])) TRUE to confirm that you understand the function. Michael Weylandt PS -- Might I suggest, if you insist on anonymity, a different handle? I'm answering on my lunch break and I'm finding that you are providing me with all sorts of icky mental images... 2011/10/3 Uwe Ligges <ligges at statistik.tu-dortmund.de>:

many thanks. I will try to figure it out. -- View this message in context: http://r.789695.n4.nabble.com/about-the-array-transpose-tp3866241p3874870.html Sent from the R help mailing list archive at Nabble.com.
