[R] problems with pan(): Indizierung ausserhalb der Grenzen = subscript out of bounds
Dear alltogether,
I tried pan() to impute NAs for longitudinal data.
The terminology in the following output follows the pan manpage. No data
are attached to this script as this may be too huge.
y = 15 responses
pred = at first just intercept was tried (later on covariates should follow)
subj = 168 different subjects with 4 to 6 observations for each subject
at time points t1, t2, ..., t6
# extract of y
> y[1:4,]

Now the error message:
> pan(y, subj, pred, xcol, zcol, prior, seed=1234,iter=1000)
Fehler: Indizierung au??erhalb der Grenzen"
# error massage = subscript out of bounds
I do not understand that. Thank you very much for every suggestion.
