Change an array into a dataset of four variables, dim1, dim2, dim3 and its elements

Hi,
?See my example below.
a<-array(1:12,c(2,3,2))

a

, , 1

? ? [,1] [,2] [,3]
[1,] ? ?1 ? ?3 ? ?5
[2,] ? ?2 ? ?4 ? ?6

, , 2

? ? [,1] [,2] [,3]
[1,] ? ?7 ? ?9 ? 11
[2,] ? ?8 ? 10 ? 12
?I want to get a result something like
dim1 ?dim2 ?dim3 ?elements
1 ? ? ? ?1 ? ? ? ?1
1 ? ? ? ?2 ? ? ? ?1
1 ? ? ? ?3 ? ? ? ? 2
2 ? ? ? ?1 ? ? ? ? 2
?I tried the data.frame and expand.grid functions, but the results are not
what i want.
?I ?think there must be an easy method to do it. Anybody can tell me that
function or method? Thanks.

...
