[R] about the array transpose

[R. Michael Weylandt]

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...
