Names of the Layers (the Third Dimension)
Description
laynames returns the names of the layers - the third dimension - of an array.
If the object does not have a third dimension (e.g., matrix), then the function
will return NULL. If the object does not have any dimensions
(e.g., atomic vector), then the function will also return NULL.
Usage
laynames(x)
Arguments
x |
array. |
Details
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.
Value
Names of the layers (the third dimension) of x. The structure is
a character vector with length = nlay(x). See details for special cases.
Examples
laynames(HairEyeColor)
a <- array(data = NA, dim = c(6,7,8,9))
laynames(a)
laynames(c(1,2,3))
