I chose the ColorBrewer palette Blues. However the resulting plot doesn't show any changes to the default. I tried several places of + scale_colour_brewer(type=seq, pal = Blues) with no effect.

[R] Displaying percentages within bars
Hello, R friends, I've got this graph: p - ggplot(diamonds, aes(x = color)) + scale_fill_brewer(type=seq, pal = Blues) + scale_y_continuous(,formatter=percent) + coord_flip() p+geom_bar(aes(fill=cut),colour='black',position='fill') Is it possible to place percentages within each field of the bars? So, for instance, the dark blue field of color = D would contain a number of about 42.0%. A second question is how to change the size of this number. Any comments are welcome!

Re: [R] Horizontal stacked 100% bars with ggplot2
Thanks, Carlos,
your solution looks nice, however, there are 4 bars instead of 2 i.e. bars are
not stacked.
Meanwhile I got a solution for that task.
So thanks for sharing your version of it!
Good luck,

Hello, R friends,
I'm trying to crack this nut:
Example Data.
pet gender
dog male
dog female
dog male
cat female
cat female
cat male
Plot Task.
Horizontal 100% bars where
y axis shows gender factor (male vs. female)
and x axis shows percentage of kind of pets (dog vs. cat)
so that % dogs + % cats are stacked in 1 bar and sum up to 100% (for each
gender group 1 bar).
How can this be done with ggplot2?

[R] Reply on ggplot2 - tricky problem
That comes really close to what I had in mind.
Thanks a lot for helping out, Justin!
Good luck,
Mario
Re: [R] ggplot2 - tricky problem
how bout:
dat-data.frame(id=1:4,city=c('berlin','munich'),likeability=c(5,4,6,5),uniqueness=c(3,4,4,4))
ggplot(ddply(melt(dat,
id.vars=c('id','city')),
.(variable,city),
summarise,
value=mean(value)),
aes(x=factor(city),y=value)) +
geom_point() +
facet_wrap(~variable)
the line drawing is a bit more tricky... Since the x values are factors
rather than continuous, fitting a line to them is kind of nonsense. It
matters which order they are in for example. If instead you want to
plot something like:
ggplot(dat,aes(x=likeability,y=uniqueness,colour=city))+geom_point()+geom_smooth(aes(group=city),method='lm')
You could draw fit lines that make a bit more sense. Forgive me if I'm over
simplifying your problem!

2. Task:
a) Facetting plots for each attitude (1 plot for likeability and uniqueness
each, horizontally on one page)
b) Showing Berlin and Munich together on x axis
c) Showing the means of Berlin and Munich on y axis (means of cities in
likeability on first plot, means of cities in uniqueness on second plot)
d) Drawing a line through mean points on each plot
Hope I could explain it understandably. Any help is appreciated!

[R] Filling a variable with unmentioned categories
Hello, list, I've been struggling with this task for a while looking for an efficient way to solve it: There are two variables 'price' and 'mentioned'. I want to 'enlarge' data so that missing price points within the price range are added to variable price. Also variable 'mentioned' is to receive values 0 in these cases. Note: Price points in original data can repeat if several persons mentioned that price point. Example: a) Original data: price mentioned 0,00 1 0,00 1 0,02 1 0,03 1 0,03 1 0,04 1 0,10 1 0,16 1 0,19 1 0,19 1 price range is 0,00 - 0,19. Some prices are missing, e.g. 0,01 . b) Supplemented data: price mentioned 0,00 1 0,00 1 0,01 0 0,02 1 0,03 1 0,03 1 0,04 1 0,05 0 0,06 0 0,07 0 0,08 0 0,09 0 0,10 1 0,11 0 0,12 0 0,13 0 0,14 0 0,15 0 0,16 1 0,17 0 0,18 0 0,19 1 0,19 1 0,20 0 Any ideas are welcome.
