<p>I am trying to analyze GSE 30321 datasets in R. However, it has 295 samples separated into two files. 
I use</p>

<pre><code>gset &lt;- getGEO('GSE30321',GSEMatrix=TRUE)
</code></pre>

<p>In this way, gset has two elements. Does anyone know how to merge the two files into one and gset has only one element with 295 files? Thank you.</p>

<pre><code>gselist = getGEO("GSE30321")
eset = combine(gselist[[1]],gselist[[2]])
</code></pre>

<p>This is usually all that is needed.  </p>
