title: How can I hide the value on the R studio or do not show the value but it can be used?
body: <p>For example:</p>
  
  <p>Script_1.R:
  <code>
  AC &lt;- 'tester'
  Password &lt;- '123456'</code></p>
  
  <p>Script_2.R:</p>
  
  <p><code>source('Script_1.R')
  dbConnect(user = AC, password = password)</code></p>
  
  <p>I wanna hide the value shown on R studio but it can be used when I need to connect DB. 
  Moreover, I wanna make Password '123456' to be shown ****** but the value is equal to 123456.</p>
  
  <p>what should I do? Thank you</p>
