Answer 1

Your axes do start at 0, and xlim and ylim are what you need to change that.

What I think you are referring to is the spacing between the axes and the plot. There are two extra parameters that allow you to change that, xaxs and yaxs.

plot (x, y, xlim=c(0,10), ylim=c(0,10),
      xaxs="i", yaxs="i") 

This should do the trick
