  Hmm.  It's surprising that you get the warning about zero response
values when you are explicitly using subset(datos, seedling>0).  Do you
by any chance have another copy of "seedling" lying around your
workspace, or have you attach()ed some data frames?  (This should
*not* break things, but it might anyway ...)

  You can try setting verbose=TRUE, although it will give you
loads of output where probably only the very end will be useful ...

  Are you willing to send me data?
