<p>This function can be used as a simple tool for creating at data base
metadata file for REDCap (called a DataDictionary) based on a given data
set file.</p>
<div class="section level3">
<h3 id="step-1---load-your-data-set">Step 1 - Load your data set<a class="anchor" aria-label="anchor" href="#step-1---load-your-data-set"></a>

<p>Here we’ll use the sample TALOS dataset included with the
package.</p>

<p>Now additional specifications to the DataDictionary can be made
manually, or it can be uploaded and modified manually in the graphical
user interface on the web page.</p>
<p>The function will transform column names to lower case and substitute
spaces for underscores. The output is a list with the DataDictionary and
a vector of new column names for the dataset to fit the meta data.</p>
</div>
<div class="section level3">
<h3 id="step-3---meta-data-upload">Step 3 - Meta data upload<a class="anchor" aria-label="anchor" href="#step-3---meta-data-upload"></a>
</h3>
<p>Now the DataDictionary can be exported as a spreadsheet and uploaded
or it can be uploaded using the <code>REDCapR</code> package (only
projects with “Development” status).</p>
<p>Use one of the two approaches below:</p>
<div class="section level4">
