Roger, If you like, go ahead and send me off-list your code and tree file. The function does not do a lot of error checking, so it is probably hanging on tip or node names; an incorrect tree structure can flummox it, too. If it is working ,it shouldn't take more than a few seconds.

I don't know what the problem could be without the data, but perhaps Gene knows?

However, when attempting to run the command scalePhylo(tr, tip.ages, node.mins), it crunches away for hours on my computer (a 2010 MacBook Pro Core i7, which is quite fast). Clearly there's something wrong. I'm afraid I don't know enough about R to debug a script. I thought I'd send this to the list in case someone other than Gene Hunt or Scott Chamberlain has had a go at using this script.
