[R] How to deal with zero-inflated proportion data?

In my previous posting
refer to playing around with distribution fitting for a particular sort
of data (see dat1 in the previous posting):
I collected absolute node degrees of some network structure and computed
the relative node degrees. This is because I want to compare different
networks at another stage.
Based on relative degrees, I attempted some distribution fitting
procedures (see my previous posting). However, I realized that zero
values (representing isolates in the network) in an otherwise continuous
variable are problematic (well, not much of a surprise).
I am wondering how to best deal with those isolates/zeros? Excluding
them entirely would be an option but isolates are relevant for my
analysis. Are there best practises for dealing with such a hybrid variable?
I am aware of censored methods (for regression analysis etc.), but not
when it comes down to distribution fitting, I fear.
