Hi
Your example is not reproducible as we do not have Biota_subset and have no idea
what is its structure. You also do not mention any error.
Most probably x and y are not what you think it is.
This works as expected.
testx<-sample(1:10,300,TRUE)
testw<-seq(1,4,by=0.01)
weighted.hist(testx,testw,breaks=1:10,main="Test weighted histogram")
Cheers
Petr
