I'd guess the most likely thing is that your margins were too narrow 
because of some previous operation.  Closing and reopening the graphics 
window should restore the default margins, you probably don't need to 
restart R, RStudio or the whole computer.

You can see the current margins by using par("mar").  The default 
setting is c(5.1, 4.1, 4.1, 2.1), i.e. a bit more than 5 lines at the 
bottom, 4 on the left and top, and 2 on the right.
