Outline of Annual Research Achievements	The biggest accomplishment has been the creation of a package for the R statistical programming language, named lefko3. This package creates a full working environment to build an analyze matrix projection models (MPMs), and to conduct projection simulations. The initial goal was to create a package that would create historical MPMs, and we have done that, but added the ability to create all of the major kinds of MPMs as well, in both historical and ahistorical formats. We have also published a major paper introducing the package, a book introducing the package and the analytical methods, given five workshops training users in it (with another scheduled for later this year), and published another five papers related to individual history (with another three papers currently being written).
