[R] access (exactly/only) one dimension of a multidimensional table

[Stefan Uhmann]

Thank you very much, Jim and Henrique,

The solution I expected but was unable to figure out myself was Jim's:
table.a[,,1] to access the third dimension.

The solution by Henrique was unexpected, bit more specific but perfect
for my purpose and very elegant.

I will make use of both in the future.

Great, thank you again!
Stefan
