Marina,

The way I would go about it would be to clarify, in order, the following
issues:

* What questions do I want to ask about the tree diameter incremental
process?

* What data do I have, or should I get, to address those questions?

* What analyses or models should I use to link the data to the process,
and hence to answer the questions of interest?

* [For statistical professionals: Will combinations of standard models
or analyses be sufficient, or do I have to do any new methodological
development?]

* What software do I need to do the data analyses or model fitting
steps?

* Are the software facilities I need available in R?

* If so, what are they and how do I use them?


>From this perspective, you seem to be starting at the wrong end.

Sorry.

Hi there,

Am try to find tree diameter increment in a hierarchical data with tree 
diameter measurements, date of measurements, in plots that are located
in 
different region. How do I do it? am very new to R.
Thanks for you help.
