title: Not able to use RSQLserver
body: <p>I am trying to use RSQLServer and first installed RSQLServer using R studio. then I am trying to use it like this.</p>
  
  <pre><code>library(RSQLServer)
  library(DBI)
  drv &lt;- dbDriver("SqlServer")
  conn &lt;- dbConnect(drv, url = "Server=**MYSERVERURL;database=DBName;trusted_connection=yes;")
  res &lt;- dbSendQuery(conn, "SELECT TOP 100 * FROM test_table (NOLOCK)")
  str(res)
  </code></pre>
  
  <p>But I am getting error everytime. Am I missing something? The Error is Object not found.? Do I need to configure any driver (probably jTDS) first? If yes, can anyone share steps to do that? Thanks. </p>
  
  <p>Error text</p>
  
  <pre><code>&gt; conn &lt;- dbConnect(drv, url = "Server=**MYSERVERURL;database=DBName;trusted_connection=yes;")
  Error in dbConnect(drv, url = "Server=**MYSERVERURL;database=DBName;trusted_connection=yes;") : 
    object 'drv' not found
  &gt; res &lt;- dbSendQuery(conn, "SELECT TOP 100 * FROM test_table (NOLOCK)")
  Error in dbSendQuery(conn, "SELECT TOP 100 * FROM test_table (NOLOCK)") : 
    object 'conn' not found
  &gt; str(res)
  Error in str(res) : object 'res' not found
  </code></pre>
  
  <p>Note: name of table and database changed. </p>
