R-Project for reproducible research on archaeological ceramics compositional data

License Script: GPL http://www.gnu.org/licenses/gpl-3.0.html

Description:

A series of routines for exploratory analysis of ceramic compositions
Designed for fully reproducible research
It is applied on two datasets: well known Roman-British Pottery published by Tubb et al.(1980) and secondly to new data from northern Iberian Peninsula pottery production centers
Based on M.J. Baxter and Jaume Buxeda i Garrigós variation matrix
Includes data visualization tools and robust statistical treatments
To use with a new dataset change the name of the csv file and run the code on each Rmarkdown file, included in the following folders and following the order:
```
   * 01_Exploration

   * 02_Group_creation

   * 03_Output
```
