the parameters in the formula for the computed tolerance. See below.
VALUE:
This function is used by the
all.equal methods to provide tolerances
for comparing standard objects with their recomputed forms.
It returns the result of
A * eps ^ B
where
eps is the larger of the machine characteristics given by
what
on the current machine and on the originating machine.
This choice of tolerance is suitable for applying the regression tests
supplied with S.
To use a different regimen for testing, either supply the
tolerance argument
to
all.equal or re-define
std.tolerance
