The bug discussed in the following year-old post suggested that the problem of clobbering attributes of top level environment objects would be fixed for 2.7 but its still in R version 2.7.2 (2008-08-25)" and also still in "R version 2.8.0 alpha (2008-10-01 r46589)" https://stat.ethz.ch/pipermail/r-devel/2007-October/047184.html The Avoiding R Bugs section of this page: http://r-proto.googlecode.com has more discussion as well as a list of some other R bugs. This can be tested by creating a package with these two files only: ---DESCRIPTION--- Package: testlazy Version: 1.0-0 Date: 2008-10-03 Title: Test lazy loading Author: G Grothendieck Maintainer: G Grothendieck <[EMAIL PROTECTED]> Description: Test lazy loading with top level objects. Depends: proto LazyLoad: yes License: GPL-2 ---R/testlazy.R--- TopLevel <- proto() --- And then testing it: library(testlazy) class(TopLevel) If its class is "environment" only then the class attribute was stripped. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
