R help - Apr 2008 - plot with standar deviation (use abline and mad())

Hi list

Maybe someone can help with the following problem (thanks in advance):
I need to analisy a long list of data time \fluoscence

I want to make one plot with standard deviation and the average data... Could
you suggest me how to make that..
The data have this distribution:
How can read and extrapolate this data?

pippo.csv

ps <- read.table(pippo.csv)
time	fluorescence
0;	 0
4.013; 62.96
6.053 ;112.3
24.14; 106.2
...
How can use a plot with standard deviation of all data: time versus fluorescen

Perhaps:

plot(ps)
with(ps, abline(v=mean(time), h=mean(fluorescence), col="red",
lty="dashed"))
