trace with reference class
No intended change. The trace method was not updated when reference class generators became functions. Should be fixed now in r-devel and 3.0.0 patched (rev 62699). Thanks for the catch. John

Hi The final line of the example in ?setRefClass induces an error:
## debugging all objects from class mEdit in method $undo() mEdit$trace(undo, browser)
Error in envRefInferField(x, what, getClass(class(x)), selfEnv) : 'undo' is not a valid field or method name for reference class "refGeneratorSlot" $trace tries to embed the trace in the generator object (instead of the generated object). Has this functionality been removed? best, kohske -- Kohske Takahashi <takahashi.kohske at gmail.com> Assistant Professor, Research Center for Advanced Science and Technology, The University of Tokyo, Japan. http://www.fennel.rcast.u-tokyo.ac.jp/profilee_ktakahashi.html
