Dear all,

i need some help with plotting.

the specific problem is the following:

#FYI
a=100
b=95
d=94.5
e=70

all=c(a,b)
all2=c(d,e)
plot(all,type="b",col="blue",xlim=c(1,4),ylim=c(20,150))
lines(all2,type="o",col="yellow")


this does work so far, but ...
i´d like to have 4 intersects, just named by characters.. no scale  
please.
the second problem is, i am trying to start the second vector where  
the first vector stops (same point on the x-axis - y is different ;) )

admittedly all this sounds quite basic, but i couldnt get a long with  
it for  a while. if somebody knows a good manual about graphics in R,  
i´d be happy if you let me know.

thanks in advance !
