r studio

Hi all,
I'm using R Studio ( I'm still a novice on R).
I'm trying to run the basic data sets that come with the package like
the mileage one
plot(mtcars$disp, mtcars$mpg)
I keep getting the error "error in plot.new(), : figure margins too large"

I think the window for my plots might be too small? I tried to resize it, but doesn't do anything. Just a blank window.
