[R] Truncating y axis

[Shravan Vasishth]

Hi folks,

I want to have a y-axis using matplot where the y axis is truncated as
shown schematically below:

(msecs)

3000 |   x
     ~ 
     ~  
800  |        x
     |
     |             x 
     |
     ----|----|----|-----------------
         1    2    3  
          Position

The ~ is supposed to stand for a curved line showing a break. The issue is
that I want to plot the points shown by the x's, but if I plot a
continuous y axis then the confidence intervals about the points at
positions 2 and 3 are not clearly visible...

Can someone suggest how this might be done? I did study the manuals and
contributed manuals first, and searched the archives and FAQs, just
couldn't find any discussion of such a situation.

Thanks much in advance,
