Vector2Array: Transforming a vector to an array

In mipfp: Multidimensional Iterative Proportional Fitting and Alternative Models

Description

Transform a vector into a multidimensional array. The transformation is done assuming that the last index of the array moves fastest. For instance, the relation between a vector v of lenght 8 and an array a of dimensions (2,2,2) is defined by v = ( a[1,1,1], a[1,1,2], a[1,1,3], a[1,2,1], a[1,2,2], …,a[3,3,3] ).

Usage

Vector2Array(vect, dim.out)

Arguments

vect	The vector of length one or more to be transformed into an array.
dim.out	The dimension attribute for the array to be created, that is an integer vector of length one or more giving the maximal indices in each dimension.

Value

An array of dimensions given by dim.out filled with the data from the input vector vec.

The inverse transformation is performed with the function Array2Vector.

Examples

# generate a vector [1,2,...,27]
v <- seq(1:27)
# transform it into an array of dimension (3,3,3)
a <- Vector2Array(v,c(3,3,3))
