<div>Hi,<br>
<br>
Yes, that is a problem that we need to sort out. I'm considering
using midpoints. It has the advantage of being easy to coerce into
numeric. In most cases that's what one needs for computations.
Using boundaries will require other(s) operation(s) to get
midpoints.<br>

<div>There is an issue, boring but may be important to agree
on now, i.e. labeling of length bins.<br>
<br>
</div>
What does a length bin mean, i.e. if the "quant" dim
represents length? and the values are 5, 10, ...?<br>
<br>
</div>
In the mixdist package these are the righthand boundaries i.e.
they represent (0,5] and (5,10]. But if they are the lefthand
boundaries then they represent (5,10] and (10,INF]. Or they
could be midpoints. One option would be to explicitly label
the bins with the boundaries and then have methods for going
backwards and forwards between parametric and non-parametric
methods. Or to have an attribute that tracks the properties.<br>
<br>
</div>
<div>Otherwise I can see a lot of time being wasted in stock
assessments. well more than normal.<br>

Hi FLR-guys,<br>
<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>
<br>
Cheers,<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>
