[R] how to plot mean+/-SD from externally calculated values

[Dan Kortschak]

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
