I use R on my university computer. When I draw something, the plot appears in the same window, on top of my console window.

How can I tell R to open the chart in a separate window?
I can not change the system files.
System Information:
- R verson 3.0.1 (2013-05-16)
- Platform: i386-w64-mingw32 / i386 (32-bit))
