Dear list, I came across a behavior that IMHO is somewhat undesired when calling '$field()': If the field name whose value you're trying to get is *not* a valid field of the Reference Class, then R doesn't stop there with an error, but scans through all enclosing environments/frames. The result is something similar to calling '|get(<objname>, inherits=TRUE)|' when you'd actually expect something like ' get(<objname>, inherits=FALSE)' to be the default (at least I do) in order to avoid undesired retrieval results.
Here's a little illustration of the behavior: http://stackoverflow.com/questions/15529251/avoiding-consideration-of-enclosing-frames-when-retrieving-field-value-of-a-s4-r Best regards, Janko [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
