R help - Apr 2004 - grid location on plot

Hello
I have
x <- c(0.5, 0.7, 3.5, 1.5, 2.5, 2.8)
y <- c(0.5, 0.8, 1.5, 3.5, 1.5, 1.5)
plot.default(x,y,type="p",panel.first=grid(5,5))
I need to plot that on a grid of 0,1,2,3,4,5 showing
the grid lines on the these numbers. how can I do
this?
e.g
how can I contorl the x and y min,max values on the
plot and the location of the grid lines?


thanks

plot(x, y, xlim=c(0,4), ylim=c(0,4))
grid() # OR ...
abline( h=0:4, v=0:4, col="lightgray", lty=3 )

help(par) gives you more options to use in plot.
grid() usually gives quite pretty results by default.

Here's one way, maybe not the best...

x <- c(0.5, 0.7, 3.5, 1.5, 2.5, 2.8)
y <- c(0.5, 0.8, 1.5, 3.5, 1.5, 1.5)
plot(x,y,type="p",xlim=c(0,5),ylim=c(0,5))
abline(h=seq(0,5),lty=2)
abline(v=seq(0,5),lty=2)
