title: 'rollupTree: Perform Recursive Computations'
version: 0.1.0.9000
doi: 10.32614/CRAN.package.rollupTree
abstract: Mass rollup for a Bill of Materials is an example of a class of computations
  in which elements are arranged in a tree structure and some property of each element
  is a computed function of the corresponding values of its child elements. Leaf elements,
  i.e., those with no children, have values assigned. In many cases, the combining
  function is simple arithmetic sum; in other cases (e.g., mass properties), the combiner
  may involve other information such as the geometric relationship between parent
  and child, or statistical relations such as root-sum-of-squares (RSS). This package
  implements a general function for such problems. It is adapted to specific recursive
  computations by functional programming techniques; the caller passes a function
  as the update parameter to rollup() (or, at a lower level, passes functions as the
  get, set, combine, and override parameters to update_prop()) at runtime to specify
  the desired operations. The implementation relies on graph-theoretic algorithms
  from the 'igraph' package of Csárdi, et al. (2006 <https://doi.org/10.5281/zenodo.7682609>).
