+<p>The following document generates a report for R packages, to satisfy the criteria of a “Released” status under the <strong>Non-GxP</strong> project. The QC report contains the following information:</p>
+<ul>
+<li>
+<strong>Specifications (specs):</strong> These can be attached to every test that the user adds.</li>
+<li>
+<strong>Traceability matrix:</strong> Contains test cases with passed, failed, or skipped expectations.</li>
+<li><strong>Uncovered or undeclared specs</strong></li>
+<li><strong>Session Info and System Configuration</strong></li>
+</ul>
+<div class="infobox warning">
+<p>Please be advised that the QC report generated for this module does not imply validation according to any other GxP criteria. The QC report only satisfies our internally developed quality checks for non-GxP criteria. For clinical reporting purposes, it is essential to note that any outputs generated using this module must be checked and verified within a validated system that adheres to the appropriate GxP guidelines.</p>

+When DTOutput(fill = TRUE), it receives a .html-fill-item class (via htmltools::bindFillRole()), which effectively amounts to `flex: 1 1 auto`. That's mostly fine, but the case where `fillContainer=TRUE`+`height:auto`+`flex-basis:auto` and the container (e.g., a bslib::card()) doesn't have a defined height is a bit problematic since the table wants to fit the parent but the parent wants to fit the table, which results pretty small table height (maybe because there is a minimum height somewhere?). It seems better in this case to impose a 400px height default for the table, which we can do by setting `flex-basis` to 400px (the table is still allowed to grow/shrink when the container has an opinionated height).

+<p>The {dv.loader} package provides a simple interface for loading data from a network file storage folder or locally. It is designed to be used with <code>.RDS</code> and <code>.sas7bdat</code> file formats. The package provides a simple function, <code><a href="reference/load_data.html">load_data()</a></code>, which loads R and SAS data files into memory. Loading data from SQL databases is not yet supported. The function returns a list named by the file names passed, and containing data frames, along with metadata for that table. By default, the function will look for files in a sub-directory <code>sub_dir</code> of the base path defined by a environment variable “RXD_DATA”. You can check if the base path is set by running <code>Sys.getenv("RXD_DATA")</code>. A single file or multiple files can be loaded at once. To make the loading process faster for large datasets, it is suggested that ‘.sas7bdat’ files are converted to ‘.RDS’ files. The function will prefer ‘.RDS’ files over ‘.sas7bdat’ files by default.</p>
