[R] rcmdr and mailing lists

[Katherine Jones]

I am trying to draw a bar chart with standard error bars for two  
groups. I was struggling in R so have now managed to get rcmdr up and  
running on my mac (although the help frequently crashes, everything  
else seems fine, if a bit sluggish; wouldn't use it for stats). This  
has allowed me to very easily create a plot of the means and standard  
errors

BUT-does anyone know if it is possible to get rid of the connect line  
between the means and to add bars to the chart?

I'm generally happy with doing stats in R but currently lack a  
package to draw very simple bar charts of means for my behavioural  
data; I have a mac and not much site licensed software.

Thanks for everyones help so far,
