[R] Tackling of convergence issues in gamlss vs glm2

[Bert Gunter]

If you do not receive a satisfactory reply to this rather technical
question -- this list is *mainly* about R programming -- you might try
directly emailing the maintainer: ?maintainer. This assumes of course that
you have thoroughly read package documentation + checked any of its listed
references (which I have obviously not).

You might also check the package code, though this often leads to C code
resources, which is kinda tough.

Cheers,
Bert
