R help - Nov 2009 - how to plot mean+/-SD from externally calculated values

Hi,

I am trying to plot a set of means+/-SD calculated by an external
program (an RDBMS) since the data set is too large to happily fit in R
(740M x 100 values - which are summarised to 100 means/SD by the DB). I
want to have a mean with whiskers at +/-1SD.

Can anyone suggest a way to do this?

thanks
Dan

Thank you for that, you have helped amazingly.Are you also able to point
me to a barplot equivalent?

It is a great puzzle to me that people do not work through the  
examples on a help page. Can you offer me a sensible explanation for  
that phenomenon?

I appreciate the frank comments; I did try the examples on the help
page, but as someone new to R programming (it still makes my head hurt)
I missed the barplot example (I noticed it but assumed - now I know
wrongly - that barplot was providing only numerical data for plotCI).

I am sorry for my mistake.
