The next step would be using traceback() to look at the call stack at
the time of the error. It should tell you the names of the functions
that were active when your code crashed.

Use getMethod() to obtain access to the S4 methods at runtime or read
the source code of the package and try to find out where did the NULL
come from. See also ?getAnywhere.

Alternatively, use options(error = recover) to land in a debugger
when the error happens and take a look at the variables as they are
(see ?browser for more information on the debugger). Which variable is
NULL despite the expectations of the code? Where did it come from?
