strat_plot_key_variables: Draw a stratigraphic plot of key geoarchaeological variables

In benmarwick/au13uwgeoarchlab: Analysing and visualising geoarchaeology data

Description

This function draws a stratigraphic plot of key geoarchaeological variables. It assumes you have already got the data from the Google sheet.

Usage

  strat_plot_key_variables(my_data, list_of_variables,
    cluster = TRUE, n = 3, ...)

Arguments

my_data	the data resulting from the get_data function
list_of_variables	a list of variables in my_data which you can get by typing names(my_data)
cluster	if TRUE, compute a coniss cluster analysis and add the results to the plot
n	the number of clusters to identify in the data. If you're plotting with clusters, you should take careful note of what number of groups is indicated by the 'elbow' in the first plot produced by this function. That will be the n value. Default is three.

Value

a stratigraphic plot

                                     n = 3)
