davidcorton/archSeries: Tools for Chronological Uncertainty in Archaeology

This package is designed to tackle a common problem in archaeology: the integration of information from multiple entities with varying chronological resolution and overlapping date ranges. It includes functions for constructing overall chronological distributions from tables of start dates, end dates, and weights, and for plotting those distributions in various ways. Distributions may be calculated either by basic aoristic analysis or by simulation. In the latter case, 'dummy sets' can also be calculated automatically based on uniformity or on a custom null model. At present the package only supports aoristic analysis/ simulation based on assumption of uniform probability within date limits, and is only designed for frequency data. In future we hope to implement: (a) ability to work with radiocarbon dates (e.g. using the Bchron package); (b) ability to specify null models other than uniform or custom, and to fit these to the data before simulating dummy sets; (c) use of beta distribution instead of just uniform.
