Hi all, I am having trouble to do a particular transition from depends to imports in one of my packages.
This packages uses 'wilcoxsign_test' from the 'coin' package. And this is the only function from the coin package that it uses (directly). (Everything works fine, as long as my package depends on the coin package.) My guess was, that I would need to only import that function from the coin package. (I.e. to move the coin package from Depends to Imports in the DESCRIPTION and in the NAMESPACE do 'importFrom(coin,wilcoxsign_test)'.) But then, calling wilcoxsign_test leads to this error: ,---- | Error in formula2data(formula, data, subset, frame = parent.frame(), ...) : | could not find function "ModelEnvFormula" `---- Now, formula2data is an unexported function in the coin package and ModelEnvFormula is a (exported) function in modeltools. So, I tried to import ModelEnvFormula from modeltools -- no avail. And I tried to import formula2data from coin -- not possible And I tried to import the whole coin package -- no avail. So, here is the question: How do I import 'wilcoxsign_test' from the coin package in a way, that it is usable? Many thanks in advance.
