line joining graphs

hi,
you can use par(xpd=TRUE)  and draw the joining line in every sub graph 
-  don't know if there is another way with simple graphs
eg:

par(mfcol=c(1,2))
plot(1,1,xlim=c(0,5),main="1st")
op<-par(xpd=TRUE)
abline(h=1)

plot(1,1,xlim=c(0,5),main="2nd")
abline(h=1)

hth.

i do to cover portions between two graphs

try par(xpd=NA)

  ?segments may be useful too

Paul Murrell's book provides such an example using Grid (figure 5.22).  
A short example is available on his website:

It may be possible to use this in conjunction with gridBase.

You may want to look at the examples for the cnvrt.coords function in the TeachingDemos package for some ideas on how to draw lines between plots.  However, it is better to use the grconvertX and grconvertY functions rather than the cnvrt.coords function (it will be deprecated one of these days).

Hope this helps,
