R help - May 2003 - Line plots with different symbols on the same line

Hello,
 
my data is an ordered list of observations where each observation is either of
condition "efficient" (coded as 1) or "non-efficient" (0) as
e.g.
 
No. Obs Condition
1 1.1 0
2 1.2 1
3 1.4 1
4 1.5 0
5 2.5 1 
etc.
 
My goal is to plot a single line with lty='o' but different symbols for
either condition whenever condition is 1 or 0, i.e. on the x-axis the
consecutive no. of observation is plotted with the obs on the y-axis as two
different symbols (e.g. pch=1 and  pch=2).
 
Is there any way to achieve this?
 
Thanks in advance
Stefan

plot(Obs, data=your_data_frame,
pch=c("*","+")[as.factor(Condition)])
see pch for details of symbols available
hope this helps.
