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
