[R] plotting simple plot with error bars

[Timur Elzhov]

Hello!

I'm novice in R, so excuse me if my question will be quite trivial.
I look through all the demos and examples, but could not find how could I
plot 'classical' simple graph with error bars.  That is, I have dataframe
with 3 columns: "x", "y" and "dy" -- how can I get points (x, y) with,
for example, short lines of length "dy" up and down from "y"?

Thanks.


Timur.
