R help - Jul 2012 - how to pool imputed data sets with latent class analysis and binary logistic regression

Dear All,

I've used mice package for my latent class analysis and binary logistic
regression

I've imputed five data sets and with long format I've added new variable
that shows latent class membership.

And then in addition to other variables, I'll use binary logistic
regression and try to pool the estimates.
However I couldn't create data.frame to mids objects, and therefore it
produced the error below:

Error in pool(fit) : The object must have class 'mira'

Do you have any suggestions? I'd appreciated if you have time and respond
my e-mail.

Bests,
Niklas
