R script used for the analysis of spatio-temporal patterns of fossil molluscs on the continental shelf of southern Brazil

The R codes provide Bayesian model fitting procedures for AAR-^14^C datasets. These codes are updated versions of the analytical scripts published by Allen et al. (2013).
Based on the ages derived from the models fitted, it is possible then to account for the time-averaging (temporal resolution of the fossil record). The time-averaging estimates are based on empirical posterior distributions, accounting for dating uncertainty, as in Ritter et al. (2017).
In addition, the R codes implements the figures produced both the cited dissertation and its derived manuscripts, like the best models fitted, age-frequency distribuitions (Histograms), its relations with sea-level oscilation in the Southern Brazilian shelf etc.
