The dimension along which to bind the arrays. |

An object of class |
abind_simple_sparse_array
automatically extends the dimensions
of the elements of ‘...’ before it combines them along the
dimension specified in MARGIN
. If a negative value is specified
first all elements are extended left of the target dimension.
extend_simple_sparse_array
inserts one (or more) one-level
dimension(s) into x
to the right of the position(s) specified in
MARGIN
, or to the left if specified in negative terms. Note that
the target positions must all be in the range of the dimensions of x
(see Examples).
An object of class simple_sparse_array
where the dimnames
are taken from the elements of ‘...’.
