[Rd] Pb with validObject(..., complete=TRUE)

Hi, When called with complete=TRUE, validObject() is supposed to work in a recursive manner. But here is a situation where it doesn't seem to be the case. Let's define a class with a validity method: setClass("PosInts", representation(ii="integer")) setValidity("PosInts", function(ob

[Rd] Sage <--> R integration

Hi R-Devel, The Sage project (http://www.sagemath.org) has been working extremely hard for several years to create a viable free open source alternative to Maple, Matlab, Mathematica, and Magma. Numerous users have requested statistical functionality. Though Sage includes scipy and numpy, which ha

[Rd] obstacles to using vectors with attributes

Hi all, I am working on an application in which we'd like to use attributes to attach simple metadata to arbitrary R objects. It is essential that all functions that will work on the original object will also work on the object after metadata attributes have been added. However, this is not al
