Hm. I don't know. I tried the following:

Creating a new Variable by:

Fbg[['F.gesamt']] <- rowSums(Fbg[11:27], na.rm=TRUE)

Which contains everything from F01 to F17 as sum().

Than I do the thing to split mothers from daugthers as you told me.

The next step i get:

dist(Muetter['F.gesamt'] - Toechter['F.gesamt'])

Which gives me some output, where I am not sure what it is. ;-(

But it looks like the thing I want, but I think I don't really have the

right data inside.

Hm. I get some syntax errors inside this. If you want you can have my

small sample I'm now createing a source file about. There I have 12

mother daugther pairs. I will get about 20 pairs within the next two

months, but then I will have my source file (loading by source("file.

R")) ready. The small sample is just to work now.

Thanks for your help,

Martin
