Another way of making functions visible to examples is to list the
package name as "Depends" in the package "DESCRIPTION" file.
Alternatively, if you precede use in "\examples" with
"library(packageName)", you should also list it as "Suggests" in
"DESCRIPTION".
Hope this helps.

The function "RandomEffectsTree" is defined in the R code for the
package. How can I refer to other functions from the package in
examples? (I have the "Writing R-extensions" PDF, so it would be
enough to point me to the right page, if the answer is in there and I
just missed it.)
You should not need to do anything special to make package functions
visible, as long as they would be visible to a normal user.
(Functions not exported in the NAMESPACE file won't be visible in the
examples.)
Are you sure you have a function with that exact name? It could be a
typo somewhere, e.g. RandomEffectTree or RandomeffectsTree.
