multiApply - Apply Functions to Multiple Multidimensional Arrays or Vectors
The base apply function and its variants, as well as the
related functions in the 'plyr' package, typically apply
user-defined functions to a single argument (or a list of
vectorized arguments in the case of mapply). The 'multiApply'
package extends this paradigm with its only function, Apply,
which efficiently applies functions taking one or a list of
multiple unidimensional or multidimensional arrays (or
combinations thereof) as input. The input arrays can have
different numbers of dimensions as well as different dimension
lengths, and the applied function can return one or a list of
unidimensional or multidimensional arrays as output. This saves
development time by preventing the R user from writing often
error-prone and memory-inefficient loops dealing with multiple
complex arrays. Also, a remarkable feature of Apply is the
transparent use of multi-core through its parameter 'ncores'.
In contrast to the base apply function, this package suggests
the use of 'target dimensions' as opposite to the 'margins' for
specifying the dimensions relevant to the function to be
applied.
