[R] Kendall's tau

[Martin Henry H. Stevens]

A search of the archives did not reveal an answer:
For basic tests of association, where one has no a priori knowledge of the 
form of the relation or of the distributions of the variables, rank 
correlation seems like a good start. Why is cor.test() with Kendall and 
Spearman options relegated to the ctest package, rather than in the base 
package? Does this suggest that the developers consider other tests of 
association more generally useful?
Thanks,
Hank
