Years ago I read about a simplified formula to answer whether I trust
someone, and in turn, something:

Trustworthiness = Competence + Character.

I think a bit of research, as the other R-help posters have so
comprehensively covered in their replies to your original question, will
convince you or anyone else you need to convince that the R-core team and
the core product of R itself rates at the top of the scale on both character
and competence.

Packages of course will not be as consistently high in the trustworthiness
continuum, but rest assured there are several that are high, which again,
you can verify yourself for your and/or your audience's needs.

Best Regards,
Bill
