<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>
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

<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>
