In testing pqR on Solaris SPARC systems, I have found two bugs that are also present in recent R Core versions. You can see the bugs and fixes at the following URLs: https://github.com/radfordneal/pqR/commit/739a4960a4d8f3a3b20cfc311518369576689f37 https://github.com/radfordneal/pqR/commit/339b7286c7b43dcc6b00e51515772f1d7dce7858 The first bug, in nls, is most likely to occur on a 64-bit

Just one followup on this one: There are two sections of code that are really similar. Your patch applies to the code in port_nlsb(), but there's a very similar test in port_nlminb(), which is called from nlminb() in R. Do you think it would be a good idea to apply the same patch there as well? It doesn't look like it would hurt, but I don't know this code at all, so it might be unnecessary. Duncan Murdoch >...

I *think* earlier versions of MASS
