Dear Arni,
thank you for the notice, which unfortunately wasn't noticed
(Easter break etc) and was too late in any case to fulfill the
criterion of a small trivial bug fix for R 4.0.0 beta (very close
to becoming RC (= "Release Candidate").
Even when type.convert() may not be used much directly (but
rather indirectly via read.table() where there's no problem), we
found it too risky to destabilize the R 4.0.0 prereleases.
As you all know there were ( / are?) still package changes
needed and a few other important "todo"s, so we had to decide to
postpone this (even for R-devel) to after releasing R 4.0.0
coming Friday.
I've committed a change to the help page which does mention that
the default for 'as.is' is planned to be changed.
Also, the help page's "Details" section, for a long time has
ended with
Since this is a helper function, the caller should always pass an
appropriate value of 'as.is'.
If useRs and package authors have followed this advice, they
won't be bitten at all.
Best regards,
Martin
