sciplot question

Hi,

I would like to have lineplot.CI and barplot.CI to actually plot  
confidence intervals , instead of standard error.

I understand I have to use the ci.fun option, but I'm not quite sure  
how.

Like this :

 >  qt(0.975,df=n-1)*s/sqrt(n)

but how can I apply it to visualize the length of the student's T  
confidence intervals rather than the stdandard error of the plotted  
means ?
