A) You should post in plain text.

B) You should precede your code with a library() call that loads the package where the effect() function resides. This is especially needed when the name "effect" is such a ubiquitous word in statstical documentation:

No documentation for ‘effect’ in specified packages and libraries:
you could try ‘??effect’

Even trying ??"effect" was not very helpful.
