R help - Oct 2007 - geom_errorbar with ggplot2

Dear All,

I am trying to build an error bar plot with ggplot2. However, even if 
the code seems to work, the plot is rather odd, with what seems to be 
a continuous line linking the different bars.

I attach below the code I used, as well as the data.
===============================================================DFrame<-data.frame(x=1:10,y=0.5*(1:10),Upper=(1:10)+0.5,
Lower=(1:10)-0.5)
p <- ggplot()
l1<-layer(data=DFrame, mapping=aes_string(x='x',min='Lower', 
max='Upper'), geom='errorbar', stat='identity')
p<-p + l1 + scale_y_continuous()

p

=======================================I wonder if anyone can help me with this.

Best,
Pedro de Barros

Hi Pedro,

That's a bug in the current version of ggplot.  I'll try to get a new
version on CRAN soon, but if you let me know what platform you're on,
I can send you a fixed version right away.
