[R] bar plot with non-zero starting level

Hi,
I want to plot grouped bars to compare 95% confidence interval estimates
from two models. Each bar represents a 95% confidence interval estimate
of a coefficient from one of the two models. Each group represents
confidence interval estimates of the same coefficient from the two models.
I think such a bar plot will nicely present whether 95% confidence
interval estimates of the same coefficient from the two models overlap.
All these confidence intervals do not start from the x axis.
I searched bar plot examples on Google. I found methods to plot bars in
groups by barplot(). I could only specify one offset for all confidence
interval estimates of the same model. I could not individually specify
an offset for each confidence interval estimate. Can someone please help
me on how I may proceed with individual offset for each of the bar in
the plot?
Thank you in advance.
Kind regards,
Xianwen
