重置R Studio中的透视图？

I'm pretty new to R programming. I'm using R studio, and all of a sudden it's no longer showing the workspace, it's only showing the console.

This is what it is supposed to look like

And this is what mine looks like now.

In Eclipse, whenever the workspace gets out of wack, I can just reset the perspective and everything it back to normal. I can't figure out how to do that in R Studio.

The default layout seemed to disappear after I restarted my computer.
