extract_from_ll_wcsl

The function <code>extract_from_ll_wcsl()</code> extracts specific elements from
a list of lists returned by the <code>get_wcs_limit()</code> function.

The Australian Regulatory Guidelines for Prescription
Medicines (ARGPM), guidance on "Stability testing for prescription
medicines", recommends to predict the shelf life of chemically derived
medicines from stability data by taking the worst case situation at batch
release into account. Consequently, if a change over time is observed,
a release limit needs to be specified. Finding a release limit and the
associated shelf life is supported, as well as the standard approach
that is recommended by guidance Q1E "Evaluation of stability data"
from the International Council for Harmonisation (ICH).

extract_from_ll_wcsl function

<dl><dt>ll</dt>
<dd>A list of lists returned by the <code>get_wcs_limit()</code>
function. The list must have three elements named <code>"cics"</code>,
<code>"dics"</code> and <code>"dids"</code>. Each of these elements have a sub-list
of the same length as the number of intercepts. Each of these sub-lists
has a sub-sub-list of the same length as the number of release limits
(<code>rl</code>).</dd>
<dt>element</dt>
<dd>A character string specifying the element to be extracted,
i.e. either one of <code>"delta.lim"</code>, <code>"delta.lim.orig"</code>,
<code>"wcs.lim"</code> or <code>"wcs.lim.orig"</code>.</dd></dl>
