[R] waller test

[Filippo Marolla]

I am trying to run a duncan-waller test, but i don't get how to implement
it.

These my scripts based on dataframe "lookout":

attach(lookout)
sqrt.res<-sqrt(res.hr.km)
bartlett.test(sqrt.res~time_slot)#no homoscedasticity
welchtest<-oneway.test(sqrt.res~time_slot)#means are differents

wallertest<-waller.test(welchtest, "time_slot", group=FALSE)

It always gives me the following error:

 cannot coerce class '"htest"' into a data.frame


What to do with this?

thanks
