rollApply
(Package: rowr) :
Applies a function over a rolling window on any data object.
Simple generalized alternative to rollapply in package zoo with the advantage that it works on any type of data structure (vector, list, matrix, etc) instead of requiring a zoo object.

vectorize
(Package: rowr) :
Vectorize a scalar function to work on any R object.
Robust alternative to Vectorize function that accepts any function with two or more arguments. Returns a function that will work an arbitrary number of vectors, lists or data frames, though output may be unpredicatable in unusual applications. The results are also intended to be more intuitive than Vectorize.

rowApply
(Package: rowr) :
Applies a function row-wise on any data object.
Essentially functions as a MARGIN=1 apply apply but also works on data objects without 2 dimensions such as lists and vectors.

coalesce
(Package: rowr) :
A more versatile form of the T-SQL code{coalesce()
Little more than a wrapper for vectorize, allows for duplication of SQL coalesce functionality, certain types of if-else statements, and apply/Reduce combinations.

cbind.fill
(Package: rowr) :
Combine arbitrary data types, filling in missing rows.
Robust alternative to cbind that fills missing values and works on arbitrary data types. Combines any number of R objects into a single matrix, with each input corresponding to the greater of 1 or ncol. cbind has counterintuitive results when working with lists, cannot handle certain inputs of differing length, and does not allow the fill to be specified.
