zbind {multiplex}

Bind Matrices and Multidimensional Arrays

Description

A function to combine or bind matrices and multidimensional arrays.

Usage

zbind(..., sort, force)

Arguments

...

One or more arrays having two or three dimensions

sort

(optional and logical) sort array according to labels?

force

(optional and logical) force binding arrays with different dimensions?

Details

Function zbind is for stacking for instance two-dimensional arrays into a single three-dimensional object to represent a multivariate system structure. Both square and rectangular arrays are supported provided that the dimensions in the input are equal, and data frames should be transformed into arrays for the binding. The dimnames in the array output correspond to the names of the first array in the input, and a warning message is given when the dimnames are NULL.

Value

Usually a three dimensional array

Warning

Arrays without dimnames are not supported.

Note

Argument force must be activated for matrices and arrays with different dimensions and a message is given.

Examples

## create the data: two sets with a pair of binary relations 
## among three elements
arr1 <- round( replace( array( runif(18), c(3 ,3, 2) ), array( runif(18),
        c(3, 3, 2) ) > .5, 3 ) )

arr2 <- round( replace( array( runif(18), c(3 ,3, 2) ), array( runif(18),
        c(3, 3, 2) ) > .5, 3 ) )

## bind the data sets
zbind(arr1, arr2)
