[R] Checking a (new) package - examples require other package functions

After adding the right functions to the NAMESPACE file, I am now getting a different error:
Error: package/namespace load failed for 'REEMtree'
2: stop(gettextf("package/namespace load failed for '%s'", libraryPkgName(package)),
call. = FALSE, domain = NA)
1: library(package, lib.loc = lib.loc, character.only = TRUE, verbose = FALSE)
I have attached the NAMESPACE file in case that is where the problem is.
Thanks again for your help!

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.
