Hi Dears,

the model below has been ran standardly, but while using augPred I receive
an error message

> cd4CORR$call
*lme.formula(fixed = cd4 ~ rt + age + pharmac + haartd, random = ~rt |
    id, correlation = corGaus(form = ~rt), subset = which(cd4 <
    2200), method = "REML", na.action = na.omit)
*
> cd4CORR$dims
$N
[1] *7023*

$Q
[1] 1

$qvec
[1] 2 0 0

$ngrps
 id   X   y
*868*   1   1

$ncol
[1] 2 6 1

> plot(augPred(cd4CORR))
*Errore in augPred.lme(cd4CORR) :
  Data in cd4CORR call must evaluate to a data frame
Errore in plot(augPred(cd4CORR)) :
  error in evaluating the argument 'x' in selecting a method for function
'plot'
*


..any hint is well appreciated...
and I thank in advance..
