change_tail_compression

*The new tail_compression 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, a
negative value indicates to SS3 to ignore it (not use t

tail_compression

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

A logical value indicating if the altered file should be
written to the disk. The default value is <code>TRUE</code>.

write_file

This function replaces the tail compression 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>tail_compression</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>tail_compression</code>. A suggested case letter is
<code>T</code>.

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

change_tail_compression 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.
