Hi
Difficult to without knowing what objects you are operating your
functions.
I get
> test.functional.t(1:10,1:10,3,4)
Error in res.em1$eta : $ operator is invalid for atomic vectors
> moderated.functional.t(1:10)
Error in testStatistics["numerator", ] : incorrect number of dimensions
And without suitable objects for those functions to operate it is
impossible to come with reasonable suggestion.
Anyway there is a function on your system which is called testStatistics
and you can not subset functions, hence your error. I did not find this
function in R pacages but I can not say that it is really not there.
You can get rid of this function by
rm(testStatistics)
Regards
Petr

testStatistics
