R help - Oct 2011 - ggplot2: changing default colors of boxplot

Hi,

I wanted to change the default colors appearing in boxplot. For example, the
following code (from the package/documentation):

==========library(ggplot2)

p <- ggplot(mtcars, aes(factor(cyl), mpg))
p + geom_boxplot(aes(fill = factor(am)))

==========
Gives the default colors. What do I need to do to modify this so that:

1. Change the colors from green and red to blue and black
2. Only have the outline of the boxplot colored (and not fill in the box)


thanks,

Hi:

Try this:

p <- ggplot(mtcars, aes(factor(cyl), mpg))
p + geom_boxplot(aes(colour = factor(am)), fill = 'white') +
     scale_colour_manual('am', values = c('0' = 'blue',
'1' = 'black'))

HTH,
Dennis
