Simplified parallel coordinate display of all Cnoc Coig data after partial grand tour. Simplified scatterplot matrix of all Cnoc Coig data after partial grand tour. The coloring is as in Figure 12. A density plot of the circled scatterplot is shown in the upper right. Dotplots of all variables for all 149 modern samples from known sampling locations.
Bright colors represent many points and dark colors only a few points.
We apply the classification rule of training data to the entire data set of 226 samples. Those points are classified by using the classification rule based on the training data for variable .355 - .50mm. From the position of the two groups it can be concluded that dune sands of group 12 are much finer since these samples have heavier weights from the finer sieves and lighter weights from the coarser sieves.
