Subject: [R] Error Bars ggplot2

Hello,

I'm attempting to plot error bars side by side rather than stacked on top
of each other with ggplot2.  Here is the sample code I am using:

#Code

#Data
spd<-c("s","f","f","s","f","s","s","s","f","f","s","f")
r<-c(4.9,3.2,2.1,.2,3.8,6.4,7.5,1.7,3.4,4.1,2.2,5)

#Turn spd into a factor
spd.f<-factor(spd)

#Place data into a data frame
data<-data.frame(cbind(spd.f,r))

#Load ggplot2
library(ggplot2)

#Create plot
pd<-position_dodge(.2)
myplot<-ggplot(data,aes(x=spd,y=r,colour=spd))+
  geom_errorbar(aes(ymin=3,ymax=5),width=.1)+
  geom_point()+
  geom_errorbar(aes(ymin=1,ymax=6),width=.1,colour="black",position=pd)
#Display plot
myplot

I have attached a plot that my sample code produces.  As you can see the
error bars are stacked.  How can I get them to plot side by side?

Thanks
