I want to take slices of a multi-dimensional table (or array) without
knowing the number of dimensions in advance.

 

As a test I tried using (in this example a 3d table):

 

     do.call(`[`, list(tbl, x,NULL,NULL)] 

 

where I built the list on the fly. It works great as long as I only want the
first dimension however when I try a different dimension, say with
list(tbl,NULL,x,NULL), I get "<0 x 0> matrix" as the result. I thought this
was because I wasn't calling the right function but there is no `[.table` or
`[.matrix` or even `[.array`.

 

Am I going about this the wrong way?
