I've finally narrowed down a puzzling problem: here is the short test case.
tmt34% R --vanilla R version 2.10.0 (2009-10-26) Copyright (C) 2009 The R Foundation for Statistical Computing ISBN 3-900051-07-0 > temp <- matrix(runif(50), ncol=2) > t(temp) %*% temp [,1] [,2] [1,] 7.916016 6.049698 [2,] 6.049698 7.650694 > library(kinship) Loading required package: survival Loading required package: splines Loading required package: nlme Loading required package: lattice > t(temp) %*% temp `__Deferred_Default_Marker__` ----------------------------------------- Within the library is a definition of %*% for bdsmatrix objects, which is perhaps the issue. But I'm only guessing since I don't have a clear idea what the error message means. Any hints are appreciated. The new coxme/bsdmatrix packages need only a couple more functions to be a complete replacement for kinship, at which point we will depreciate it. (Pedigrees and plotting were finished last weekend!) But I can't quite do that yet. The error does not arise with these newer libraries. There have been no changes to kinship for some time.
