Test<-read.table("TestRFemMalBivariat1.csv",header = TRUE, sep = ";")
Now I try to perform a similarity analysis with the dsvdis function
of the labdsv package with the sorensen-Index.
My first question is if all zeros in my table are seen as missing

into other numbers?
Secondly I tried to perform the analysis as simple as possible, after
changing the characterstates into 1 and 2 with this code:
DisTest<-dsvdis(Test, index = "sorensen")
But I always get back this error message:...
