R help - Apr 2008 - grid() : start values?

Hi,
is not there any way to tell grid() the starting value? With nx,ny
I get the right number of grid cells, but not on the exact
values I would like them. (I know I can do it with abline(), just
asking for an easier way, i.e. grid(nx,nx,start.x,start.y))

An alternative way (which would solve another problem) would be making 
the axes coincident with the rectangular plot region, that is, if ploting
plot(0:10,0:10)

get (0,0) just on the bottom down corner of the rectangle. I've tried 
with several par() and could not find the way.

Thanks

See the help page:

If more fine tuning is required, use 'abline(h = ., v = .)'
      directly.

Just use

abline(h=seq(starty, stopy, len=ny), v=seq(startx, stopx, len=nx))
