replicated values on y-axis in geom_pointrange / geom_crossbar
Stefan
I have the following problem:
df<-data.frame(treatment=c('A','B','C','D'),
outcome=c(266.5,268.3,267.5,268.8), se=c(0.2449,0.2136,0.1872,0.2347))
> df
treatment outcome se
1 A 266.5 0.2449
2 B 268.3 0.2136
3 C 267.5 0.1872
4 D 268.8 0.2347
Instead of using bar graphs I'd like to present the data as
pointranges or crossbars:
ggplot(df, aes(x=treatment, y=outcome))
+geom_pointrange(aes(ymin=outcome-se, ymax=outcome+se))
When looking at the y-axis the value 268 is repeated 3 times. Do you
have any explanations for that? I probably just missing something
obvious?!
Thanks!

Your example works fine (axis shows 267.5, 268.0, etc.) on my system.

But I just tried it again, deleted my workspace and started a new R
session and this is what I get:

ggplot2 0.8.9 doesn't need scales and it may induce some problems.
update your ggplot2 to 0.9 or
detach("package:scales")
and then plot.

That did the trick! Awesome! I already updated once to 0.9 and loaded
the scales package via my .Rprofile file. Then 0.9 got pulled and I
had to change everything again but forget to also change the .Rprofile
file. So, for now I will just detach and update once my work is
submitted.
