I‘d be grateful for an advice. I have a set of 45 radiocarbon dates from inhumation and cremation burials from cemeteries distributed within a certain region well defined as an archaeological culture. I have a good reason to presume that inhumation was practiced in the initial stage of the culture, and the earliest cremations appeared somewhere in the south of the region and that there had been a certain period of spread of cremation towards the north until it became dominant throughout the whole region. I can also presume some stages of biritualism in micro-regions throughout this time and space, as it can be seen in some individual cemeteries. This is, however, the model created only on relative archaeological chronology.
What I‘d like to create is some radiocarbon-based visual model of change of the burial rite. Maybe anyone has made an analysis with a somewhat similar goal and would suggest a solution. I was thinking of two phases for both the inhumations and cremations. But three issues: 1) how to include both the diminishing inhumanions and cremations replacing them into one model, 2) how to achieve a good visual output for this, 3) and last but not least, how to add the spatial dimension of the process (maybe to simply arrange the dates after the cemeteries‘ Y coordinate – S-N and N-S?).
Not sure if I managed to express myself clearly and if at all this can be achieved within a single script. But anyway, thank you in advance for any idea.
May I ask little more assistance with the code. I was thinking this would be correct to achieve what I seek? But I’m not sure how can I avoid using boundaries. In my case, start of inhumation and end of inhumation are beyond my interest.
And I came across a very basic issue. I've never used ArchaeoPhases. Seems it can be helpful with spatial analysis. I was trying to use the online version, but how can I import the rax data from OxCal?
Thanks in advance and all the best,
Thank you for interesting discussion. I’ve made experiments in all ways you suggested and arranging my dates randomly and after the N-S and S-N coordinates. Yes, it depends a lot on how much related you suppose your samples are, and yes, there can never be samples completely unrelated in archaeology. Moreover, you can consider the same set of samples both related or unrelated, depending on the context and, above all, what question you have. The very idea of something “being related” is one of the fundamental in archaeology.
Now I’m getting to the ways of spatial analysis. Thank you once again for a good advancement of my knowledge.
