Hi
Im attempting to build a sample variogram for 300 obersvations
of longitudinal data. So what I need to do is compute the half
squared differences between pairs of residuals (for instance
if a subject has 4 obersvations, this is 4 choose 2 paird differences)
for each subject.
Also, then I
1.The simple problem ist that i have different Samples , from
which i make repeated measurements (each sample is measured 6
times) and i repeat this experiment over several Days, so i
get the lme grouping term random=~1|Days/Sample.
I would rather specify this as: random= ~ 1 |
A variable is considered to be nested when it is unique within that
combination. i.e. if your measuring Apparatus was different at each sample.
Hence, as Lorenz suggested it is reasonable to treat Apparatus as fixed,
specially if you are considering making comparisons between the 2 apparatus.

Hi YiYao,
you need the `?panel.abline()' function, somehing like:

inside the `histogram()' function could do the trick.
I hope
