title: How to use NCBI gene database in biomaRt R package
body: <p>I'm not very expert with R but I'm trying to learn ho to use the biomaRt package to find genes located in my regions of interest.</p>
  
  <p>I've managed to produce a valid output using the ensembl dataset with the following code:</p>
  
  <pre><code>&gt; mart= useMart(biomart="ensembl",dataset="hsapiens_gene_ensembl")
  &gt; results &lt;- getBM(attributes =c("chromosome_name","start_position","end_position",
  "band","hgnc_symbol","entrezgene"), filters = c("chromosome_name","start","end"),
  values = list(1,226767027,227317593), mart=mart)
  </code></pre>
  
  <p>I know that the "entrezgene" corresponds to the NCBI gene ID, but I would like to have the GENE NAME from NCBI.</p>
  
  <p>Is there a way to use biomaRt connected to NCBI database and retrieve that informartion?</p>
  
  <p>Thank you in advanced.</p>
