change_lcomp_constant

*The new value to be used. Must be a numeric value, as
a proportion. For example 0.1 means 10 percent. See the SS3 manual for
further information. A NULL value indicates no action resulting in using
the current value, and a value of 0 will throw an error 

lcomp_constant

An SS data list object as read in from
<code><a href="/link/SS_readdat?package=ss3sim&version=0.9.0&to=r4ss" rd-options="r4ss" data-mini-rdoc="r4ss::SS_readdat">SS_readdat</a></code> in the <pkg>r4ss</pkg> package. Make sure
you select option <code>section=2</code>.

dat_list

A string providing the path to the output SS3 <code>.dat</code> file.

dat_file_out

write_file

This function replaces the robustification value for length composition data
in a <code>.dat</code> file that was read in using <code><a href="/link/SS_readdat?package=ss3sim&version=0.9.0&to=r4ss" rd-options="r4ss" data-mini-rdoc="r4ss::SS_readdat">SS_readdat</a></code>
with those specified in
<code>lcomp_constant</code>. It then writes a new file with name <code>dat_file_out</code>
into the working directory. If used with <code><a href="/link/run_ss3sim?package=ss3sim&version=0.9.0" rd-options="" data-mini-rdoc="ss3sim::run_ss3sim">run_ss3sim</a></code> the case
file should be named <code>lcomp_constant</code>. A suggested case letter is
<code>C</code>.

The ss3sim package develops a framework for fisheries stock
    assessment simulation testing with Stock Synthesis 3 (SS3).

change_lcomp_constant function

All function argument descriptions that start with an asterisk (*) will be passed
through the case files to <code><a href="/link/run_ss3sim?package=ss3sim&version=0.9.0" rd-options="" data-mini-rdoc="ss3sim::run_ss3sim">run_ss3sim</a></code>. If one of these arguments
is not specified in a case file, then a value of <code>NULL</code> will be passed,
which may or may not be an appropriate value. Other arguments will be ignored
if specified.

change_lcomp_constant: Set the robustification constant for length composition data.
