[R] ggplot and xlim/ylim

[hadley wickham]

Hi Jiho,

To figure this out, you need to think about exactly what you are doing
when you change the limits - what part of the plot are you changing?
You are changing the scales, and if you have a look at
http://had.co.nz/ggplot2/scale_continuous.html, you'll see you need
something like:

+ scale_y_continuous(limits=c(0,10)

Remember, you can also modify qplot in the same way as ggplot:

qplot(...) + geom_point() + ...

Regards,

Hadley
