I am exploring the result of clustering a large multivariate data set
into a number of groups, represented, say, by a factor G.
I wrote a function to see how categorical variables vary between groups:
ddisp - function(dvar) {
+ csqt - chisq.test(G,dvar)
+ print(csqt$statistic)
+
Thanks for these suggestions, Professor Ripley. It's interesting that
the function parameters in R are not truly dummy as they can effect
the result of a function.
