round() doesn't (PR#1139)
...s to be specifically for negative
"digits". This is in 1.3.1 on Solaris 2.6 (full description at bottom).
[Apologies for making everyone read this 3 times; my bug.report() burped.]
Peter Dalgaard <p.dalgaard@biostat.ku.dk> says the problem is in fround.c,
which reads in part:
pow10 = R_pow_di(10., dig)
...
return sgn * (intx + R_rint(x * pow10) / pow10);
and (says Peter),

I'm not up to patching C code, but I will say that a workaround is:

back-transform predictors for x-axis in plot -- mgcv package
My question is related to plot( ) in the mgcv package. Before modelling
the data, a few predictors were transformed to normalize them.
Therefore, the x-axes in the plots show transformed predictor values.
How do I back-transform the predictors so that the plots are easier to
interpret?
Thanks in advance,
Suzan

significant digits (PR#9682)
I came to report this same bug and found it already in the trash, but
I slightly disagree with that assessment. If it's not a bug, then
perhaps it's a feature request. Comments at the end.
