Apparently the panel function is executed for each subset of data in the
main dataset (specified by the conditioning variable, 'site' in my
example), and the 'subscripts' keyword passes a vector of the
corresponding row n
If your series is nearly regular, that is it is regularly spaced
except for a few missing points then as.ts(z) will convert it to a
regular ts series and as.zoo(as.ts(z)) does that and converts it back.

Dear all,
I have just sent a message asking about poLCA but I thought of another question
I wanted to ask. I get the G^2 statistic in my output and want to test for its
significance. I get that the degrees of freedom for the test are (S-1-p) where
S is the number of different patterns observed
Note that if you use Rterm.bat in http://batchfiles.googlecode.com in
place of Rterm.exe then you won't have to adjust the Run action when
you upgrade R. Rterm.bat is a single self contained Windows batch
file that you simply place on your Windows path.

The `fminsearch' in Matlab uses a version of the Nelder-Mead simplex search
algorithm, which is a derivative-free search technique. The Nelder-Mead is
also the default algorithm in optim(). Therefore, you can simply call optim()
