[R] xyplot and separate abline per plot

[Karin Lagesen]

Hello list!

I have a set of data like this:


> alldata[1:5,]
     breaks numbers         disttype moltype            type
1 0.0000000    6598 Gapped Distances      5S Between species
2 0.4066667       0 Gapped Distances      5S Between species
3 0.8133333    5228 Gapped Distances      5S Between species
4 1.2200000       0 Gapped Distances      5S Between species
5 1.6266667    9702 Gapped Distances      5S Between species
> levels(alldata$disttype)
[1] "Gapped Distances"   "Ungapped Distances"
> levels(alldata$type)
[1] "Between species" "Same species"   
> levels(alldata$moltype)
[1] "16S" "23S" "5S" 
> 

Which I plot like this:

xyplot(numbers~sqrt(breaks)|moltype+disttype, groups = type, data = alldata)

This results in a plot consisting of six different panels. Now, I have
a set of six different values that I would like to incorporate into
these plots through a vertical line in each panel (one separate value
per panel). I think I can do this through panel.abline somehow, but I
don't know how to incoporate that into the xyplot command, and I don't
know how to specify which values I want plotted in each plot.

I hope I am able to convey what I want:)

Thanks in advance,

karin
