[R] ggplot2 font size problem

[dhzdhz]

x=c("abcdefghijklmn", "opqrstuvwxyz")
y=c(1, 2)
df=data.frame(name=x, value=y)
p=ggplot(df, aes(name, value))+geom_point()
grid.gedit(gPath("xaxis"), gp=gpar(fontsize=8))
print(p)

It doesn't work. I have to print(p) before I change the font size.
Furthermore, this change will be overwritten by default if I print(p) again.
And the worst is that it works very ugly in y axis.

Instead

p=ggplot(df, aes(name, value))+geom_point()

I used 

p=ggplot(df, aes(value, name))+geom_point()
grid.gedit(gPath("yaxis"), gp=gpar(fontsize=8))

The whole label and ticks are moved left due to smaller fonts. However, the
figure doesn't. And now the ticks and labels are detached from the axis.

Can I change the default setting?

Thanks

This only works AFTER I plot out the figure. And if I replot again, the
fontsize is back to default setting.
