<br>
As you know I am not an active FLR user, but last year I showed some interest
in whether you have size-based stuff in FLR (see attached email). In the
meanwhile Coilin Minto and myself have been working on something (also attached
- note this is a draft of the idea; at the moment we are working on the code to
get the final graphs out) which we are coding in R but which could/should
eventually been done in FLR. Perhaps you are interested.<br>

Hi,<br>
<br>
Following Laurie's suggestion I've started a git repository for length<br>
methods in FLRhttps://<a href="http://github.com/ejardim/FLMethLen" target="_blank">github.com/ejardim/FLMethLen</a><br>
<br>
Maybe our first task should be o write down what we're doing with length<br>
data. Laurie's working on ALKs, so I guess you're interested in<br>
converting length frequencies to ages for stock assessment !? We (a4a)<br>
are working on OMs and how to generate them from length based data so<br>
that uncertainty on the growth model can be included in the MSE. Sarah<br>
and Colin Minto are working on selectivity. What else ?<br>
<br>
Best<br>
