title: How to change format values in a Pie Chart made by plotly (in R)
body: <p>First of all thank you for spending a little bit of your time helping me to solve this issue.</p>
  
  <p>I am getting started in <code>plot_ly</code> through R and I am struggling when trying to change the format of the values of my Pie Chart (I want them to be showed in the plot as currency "$" format). </p>
  
  <p>So far my code looks like:</p>
  
  <pre><code>data &lt;- data.frame(Level = c("Receipt","Disbursement"),Amount = c(1000,2000))
  
  name_dataset &lt;- "Overview"
  
  plot_ly(data=data, labels = Level, values = Amount, type = "pie", textinfo= "label+percent", 
          hoverinfo = "label+percent+value", outsidetextfont = list(color = "white")) %&gt;% layout(title = paste0(paste(unlist(strsplit(name_dataset,"_")),collapse = " ")))
  </code></pre>
  
  <p>Thank you for your help!</p>
