Heja, I hope someone is still there to help me:
How can I somehow merge/combine matrices to get such a result: Matrix A A B x1 1 0 x2 1 1 Matrix B C D x3 1 0 x4 0 1 Resulting Matrix? A B C D x1 1 0 0 0 x2 1 1 0 0 x3 0 0 1 0 x4 0 0 0 1 Does anyone see this probably obvious solution with R how to do this? Sorry if this question is silly...it's too hot here to think properly ;O) Thanks! cheers Marten -- -------------------------------------------------------------------------------------------- Dr. Marten Winter / Researcher Biozönoseforschung / Community Ecology Helmholtz-Zentrum für Umweltforschung GmbH - UFZ Helmholtz Centre for Environmental Research GmbH - UFZ Theodor-Lieser-Str. 4 / 06120 Halle (Saale) / Germany Telefon +49 345 558 5316 / Fax +49 345 558 5329 marten.win...@ufz.de / www.ufz.de/index.php?en=7081 Sitz der Gesellschaft: Leipzig Registergericht: Amtsgericht Leipzig, Handelsregister Nr.
