Thanks Bert!

I have right now a dataset that looks like this:

> tail(partition, 3)

element run logfO2 TC buffer xAn sdXan Di Disigma

416 Al 36 -0.68 1180 AIR 0.734 0.007 2.10 0.02
417 Ca 36 -0.68 1180 AIR 0.734 0.007 1.29 0.02
418 Na 36 -0.68 1180 AIR 0.734 0.007 1.16 0.06

Basicaly I would like to insert error bars into a xyplot like this

> xyplot(log10(Di) ~ TC | element.ord, groups=buffer.ord, #pch=16,

+ #subset=no1140,
+ data=partition,
+ auto.key=list(columns=3),
+ )

How could llines, lsegments or perhaps panel.arrows look like?

I appreciate any help on this.

Best regards,

Mario
