Package: insitu 0.1.3.9023

insitu: By-Reference Routines for Numeric Vectors

Using by-reference semantics, functions in this package are crafted to modify the input objects in-place and avoid allocating new memory. By avoiding memory allocations (and the associated garbage colection these require), operations performed by-reference can be faster than those performed with R's default copy-on-modify semantics.
