[R] Function not found, maybe respective package has to be put in environment?

[Uwe Ligges]

You have to load tseries on the nodes, not only on the master, i.e.:

clusterEvalQ(cl, library("tseries"))

Therefore, I think the package tseries has to be put somehow in the environment where also the package stats is because the function mean() works but the function adf.test() not.
