unwrap.array: Unwrap an array, matrix or a vector to an array of more dimensions

Description

Unwrap an array, matrix or a vector to an array of more dimensions. This is done by splitting up each dimension into several dimension based on the names of that dimension.

Usage

## S3 method for class 'array}(x, split=rep("\\.", length(dim(x))), drop=FALSE, ...)':
unwrapundefined

x{An array or a matrix.}
 split{A list or a character vector.
   If a list, it should contain functions that takes a character
   vector as the first argument and optional ... arguments.
   Each function should split the vector into a list of same length
   and where all elements contains the same number of parts.
   If a character vector, each element split[i] is replaced by
   a function call
   function(names, ...) strsplit(names, split=split[i]).
 }
 drop{If TRUE, dimensions of of length one are dropped, otherwise not.}
 ...{Arguments passed to the split functions.}

Returns an array.


Although not tested thoroughly, unwrap() should be the inverse
  of wrap() such that identical(unwrap(wrap(x)), x) holds.


See ?wrap.array for an example
