title: Resize plotly R ggplotly
body: <p>I'm having some trouble using the plotly R package. I'm very new to plotly but I loved that I could use ggplot-like syntax so I'm trying to make it work.</p>
  
  <p>I created a faceted plot where you can hover over a datapoint and see details about that record. I'm very happy with the plot, but I'd like to resize it so the y-axis of each plot isn't so short, as in I'd like to adjust the height and width of the overall plot. </p>
  
  <p>As is, I can't figure out how to override the default sizing and I'm pulling my hair out because all of the examples I can find use plot_ly() rather than ggplotly(). I'd rather not rebuild the plot just to adjust the sizing unless I need to. </p>
  
  <p>The code I'm running currently is really simple:</p>
  
  <pre><code>plot &lt;- ggplot(data = counts_country, aes(x = Year, y = Count, color = Region, text = paste("country:", Country))) +
    geom_point(size= 2, alpha = (1/2)) + 
    facet_wrap(~ Region, ncol = 1)
  
  (gg_plot &lt;- ggplotly(plot))
  </code></pre>
  
  <p>You can see exactly what I'm working with here:

  <p>I tried adjusting the plot to show two rows of plots but still have trouble because the year labels get smashed together. Resizing seems like all I need.</p>
