Some time ago Deepayan and I created a package called MEMSS for the
data sets from the nlme package as data frames but not groupedData
objects. Because of advances that Deepayan has made in lattice
graphics many of the specialized plotting methods for the groupedData
objects are no longer needed.
Does this include datasets such as CO2 and ChickWeight
which are in the datasets package?
Could you post a list of the specific datasets you are referring to
so there is no confusion what this is about.

I am only referring to the d
On a related note CO2 and ChickWeight in datasets have nlme
specific attributes so either those datasets themselves should be
moved to nlme or the nlme specific attributes removed in datasets
as well.

The qt function for df=1 is implemented as...
q = - tan((P+1) * M_PI_2);
Adding 1 kills accuracy for P near 0. A better way is to use
q = cot(P * M_PI_2);
or
q = 1/tan(P * M_PI_2);
