nlay
returns the number of layers - the third dimension - of an array.
If the object does not have a third dimension (e.g., matrix), then the function
will return NA with typeof = integer. If the object does not have any dimensions
(e.g., atomic vector), then the function will return NULL.
nlay(x)
x |
array. |
R does not have standard terminology for the third dimension. There are several common terms people use including "height" and "page". I personally prefer "layer" as it makes sense whether the user visualizes the third dimension as going into/ontop a desk or into/ontop a wall.
The number of layers (the third dimension) of x
. The structure is
an integer vector with length = 1. See details for special cases.
