R help - Jan 2013 - ggplot not showing all the years on the x-axis

Dear R helpers,

I am currently having hard time fixing the values on the x-axis of a plot
with ggplot: even though I have 12 years, ggplot plots only 3 of them.
Here is my example:

library(ggplot2)
ii <- 2000:2011
ss <- rnorm(12,0,1)
pm <- data.frame(ii,ss)
tmpplot <- ggplot(pm, aes(x = ii, y = ss))
plot <- tmpplot + geom_line()
plot

In my case, ggplot reports on the year 2000, 2004 and 2008 on the x-axis,
but I'd like to have all the years from 2000 to 2011. I know how to fix
this with the standard plot in R, but for consistency I'd like to use
ggplot.
Can anyone help?
thanks in advance,
f.

Hi,this is a question about how to set the scale,try this
add a scale_x_discrete() like that:

plot <- tmpplot + geom_line()+scale_x_continuous(breaks=ii)
