Hi
In new ggplot2 version following works too
p + geom_boxplot(aes(fill = factor(cyl))) +
labs(fill = "Cylinders") + ylab("Miles per Gallon")+xlab("Number
of
Cylinders")
Regards
Petr
Yes you can do all of the things you want.
Below is a start, to give you an idea of how to approach some of it.
====================================================
library(ggplot2)
p <- ggplot(mtcars, aes(factor(cyl), mpg))
p <- p + geom_boxplot(aes(fill = factor(cyl))) +
labs(fill = "Cylinders") +
scale_y_continuous("Miles per Gallon") +
scale_x_discrete("Number of Cylinders")
p
============================================================
Have a look at
ackoverflow.com/questions/3606697/how-to-set-x-axis-limits-
in-ggplot2-r-plots for x and y axes limits.
It took me a while to realise it but, generally, I find that it is not
hard to find examples of what you need by just googling something like
:ggplot2 set x and y limits or ggplot2 geom_bar colour and so on.
The ggplot2 and geom_XXX are pretty unique on the internet and search
results usually are not too bad.
You may also want to subcribe to the ggplot2 group on google groups.

Also, it is possible to change "ylim" also?

Dear all,
I have a few questions regarding the boxplot output from the
"geom_boxplot" function.
Attached is the output I get. Below are my questions:
1. How can I define the xlab and ylab myself?
Also I would like to remove "factor(variable)"
line on the right side.
2. How can I define the colors of the boxplots myself.
For example, I want to use blue for
"LR", green for "pair" and purple for "BR1".
Thanks so much!
Hannah
