I was too optimistic - the complexity is O(E*log(V)) where V is the number of

It is O(|V|+|E|) to calculate unweighted shortest paths from one vertex
to all others. It is indeed O(|E|*log|V|) if you have a weighted graph.
But both of these should be reasonable for |V|=25000 and 500 sources,
you just need a fair amount of memory.
For the details see ?shortest.paths.

There might be a more elegant way of doing this but here is a way of
doing it without reshape().
df - data.frame( ID=c(1,1,1,1,2,2),
TEST=c(A,A,B,C,B,B),
RESULT=c(17,12,15,12,8,9) )
df.s - split( df, df$ID )
out - sapply( df.s, function(m)
Bert,
Yes, I am aware of that, maybe I was a bit unclear in my previous post. My
issue is not at all with interpreting data or deciding on what to do with
it. That I am quite capable of doing myself and I could perform the analyses
I want to do using other software. However, as I'm trying to

Dear all,

Thank you to Jim and Moshe. I will try the Rprof option as well as the
running the function to run on columns instead. Thank you.

Brilliant! I've just ordered your book to learn more about lattice as
its use is quite gripping despite a steep learning curve.
Many thanks,

I don't see this on Nabble, so I'll re-post. Apologies if I missed it..
Still no joy. :-(
I see a number of things that bother me.
1) str(ByEBNum$StnTraveld) says int [1:12] 1 2 3 4 5 6 7 8 9 10 ...
Even though StnTraveld - c(as.factor(1:12))

Hello,
I would like to know if mosaic plots are supported by ggplot2? If so,
can someone point me to a couple of examples or give me any pointers?
Cheers
