Representation of data in libraries

On the other hand: does it really make sense to distribute huge example
data sets as yours above?

The purpose of this example is to show that the lme methods work with
very large data sets.  These data are from a survey conducted by a
sociologist.  He fit a mixed-effects model to them using SAS PROC
MIXED.  It took five hours of cpu time on a relatively fast machine
(Pentium II 233 MHz, 64 Mb memory).  Once I decide what the model he
used is in our notation, I will try it in lme.  I am confident we
can do it much faster.

I decide to omit this data set from the standard distribution for lme
although the way that data sets are organized in R there is not much
penalty other than the disc space for including large examples that
are rarely used.

Following Thomas's suggestion of increasing the -n as well as the -v
option I was able to read the data in with its current form.
