afill
(Package: abind) :
Fill an array with subarrays
Fill an array with subarrays. afill uses the dimension names in the value in determining how to fill the LHS, unlike standard array assignment, which ignores dimension names in the value. afill() is a S3 generic, with one method, afill.default, supplied in the abind package.
adrop
(Package: abind) :
Drop dimensions of an array object
Drop degenerate dimensions of an array object. Offers less automaticity and more control than the base drop() function. adrop() is a S3 generic, with one method, adrop.default, supplied in the abind package.
Combine multi-dimensional arrays. This is a generalization of cbind and rbind. Takes a sequence of vectors, matrices, or arrays and produces a single array of the same or higher dimension.
