array(x, dim=length(x), dimnames=NULL) as.array(x) is.array(x)
dim
and naming information in dimnames.
The values in x are taken to be those in the array with the
leftmost subscript moving fastest. If there are too few elements
in x to fill the array, then the elements in x are
recycled.
as.array() coerces its argument to be an array by attaching a
dim attribute to it. It also attaches dimnames if
x has names
