To me this is not inconsistent with a list being analogous to a frame. In both cases a deep search does not take place. Thus a frame is a shallow structure and an environment defined as a frame and its ancestors is a deep structure (with respect to its parent) so I would expect that the deep structure would search deeply. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
