R help - Mar 2009 - Plot Means Line with Standard Deviation as "Whiskers"

Hi list members.

I’ll try to plot the abundance means of nine transects as lines, with five
points on each transect (A to I). I will also need to plot for each point,
it’s standard deviation (once each point will have tree replicates) as
whiskers. Another problem will be that all the points should exist for each
transect, but we know that six of the nine transects will have blanks (A1,
A2, A3, -, A5). So the line have to be interrupted and can’t induce an
inexistent value by link A3 to A5 (an example).

 

Well, unfortunately I still don’t have the data, I’m just anticipating a
future situation, and I can’t find any clear suggestion by “googling” the
issue, and I guess the help files may have something but I was unable to
find by myself.

 

Thanks in advance. Any help will be appreciated.

You could always make up some data and then show us what you have tried to do. 
I would guess you need to check out:

plot # to do the basic plot
lines # to add lines to the plot
points # to add points to the plot
arrows # can be used to give the whiskers
apply # to get the means and standard deviations
