title: Remove decimals y axis ggplot2
body: <p>I have data that looks like this, <code>df_Filtered</code>:</p>
  
  <pre><code>Product Relative_Value
  Car     0.12651458
  Plane   0.08888552
  Tank    0.03546231
  Bike    0.06711630
  Train   0.06382191
  </code></pre>
  
  <p>I want to make a bar plot of the data in GGplot2:</p>
  
  <pre><code>ggplot(df_Filtered, aes(x = Product, y = Relative_Value, fill = Product)) +
      scale_y_continuous(labels = scales::percent) +
      geom_bar(stat = "identity") +
      theme_bw() +
      theme(plot.background = element_rect(colour = "black", size = 1)) +
      theme(legend.position = "none") +
      theme(plot.title = element_text(hjust = 0.5))
      labs(x ="Product", y = "Percentage of total sell", title = "Japan 2010") +
      theme(panel.grid.major = element_blank())
  </code></pre>
  
  <p>How do i get rid of the decimals on the y-axis in the chart? So that it says <code>20 %</code> instead of <code>20.0 %</code>?</p>
