R help - Nov 2019 - (no subject)

Hi,
I would like to know what is the difference between function oneway_test
and independence_test of coin package.
You will highly appreciated

Have you read the help pages of the two functions? That is where I would start.

It's not so much that they are "different", but rather that one is
(much) more general than the other. If you look at the code, which one 
should always do in such questions, you immediately see that 
`oneway_test` calls `independence_test` after some setup of parameters.? 
You should also read ?oneway_test and ?independence_test where this is 
also clearly explained. The `oneway_test` is actually a method to do 
some of the tests that you would encounter in a traditional introductory 
statistics course in the section on "nonparametric tests". So 
`oneway_test` is just a restricted type of the more general 
"independence test" suite of methods.

methods(oneway_test)
[1] oneway_test.formula* oneway_test.IndependenceProblem*

# since the default method is not exposed, use `getAnywhere`


getAnywhere(oneway_test.IndependenceProblem)

# omitting parameter setup code

object <- do.call("independence_test", c(list(object = object),
 ??????? args))

if (is_ordered_x(object at statistic))
 ??????? object at method <- "Linear-by-Linear Association Test"
 ??? else if (twosamp) {
 ??????? object at method <- "Two-Sample Fisher-Pitman Permutation
Test"
 ??????? object at nullvalue <- 0
 ??? }
 ?? else object at method <- "K-Sample Fisher-Pitman Permutation
Test"

object
