[R] How do I move the horizontal axis in a plot so that it starts at the zero of the vertical axis?

[Jim Lemon]

Hi andrejfavia,
You probably want:

plot(x,y,ylim=c(0,2),yaxs="i")

for question [1], Have a look at the ms.polygram and my.symbols help
pages in the TeachingDemos package for question [2] and I haven't got
a clue about question [3].
