Hi Robin,
congratulations to your published article about untb ;-)
One possible explanation is that your examples use random numbers which
may be different ones during the CRAN check. I had this problem with
another package where a "rare random number event" lead to
non-convergence of optim during the package check. You may use
set.seed() as a first aid and then try to stabilize your algorithms.
BTW: untb_1.3-2.tar.gz passed the check just now on my system: R 2.7.0
Under development (unstable), svn rev 43092 (5. Oct), i386-pc-mingw32
