array(x, dim=length(x), dimnames=NULL)
as.array(x)
is.array(x)
An array with the extents specified in 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. The sole purpose of this is to make it
possible to access the dim
attribute at a later time.
is.array
returns TRUE
or FALSE
depending on
whether its argument is an array (i.e. has a dim
attribute)
or not.
