I am trying to work with my data set to graph a cluster analysis similar to this example:
Why is the line of wss-plot (for optimizing the cluster analysis) looks so fluctuated?
with a previous related thread (How to draw the plot of within-cluster sum-of-squares for a cluster?)
When I follow along with the exact code of the thread (either the Iris example, or the person asking the question's example data) I get an error when attempting to plot the output: " Error in xy.coords(x, y, xlabel, ylabel, log) : (list) object cannot be coerced to type 'double' "
The only thing I can think that is going wrong is perhaps the wrap function is not working properly. When I first attempted to do the code wrap was not recognized and so I installed the ggally package and then used the wrap function as presented in the sample codes.
Any help would be appreciated as I feel like there is some obvious and simple fix that I am missing.
