Are you referring to the zeroinfl() function in the countreg package? If
so, I think
predict(fm_zinb2, type = "zero", newdata = some.new.data)
will give you pi for each combination of covariate values that you
provide in some.new.data
where pi is the probability to observe a zero from the point
Ah, thanks all. Guess I missed the message before they started the
maintenance.

date appears to be a character variable, and R is treating it as such.

I think R did what you asked, but if you want to be able to order
records by date, in temporal order, you need to tell R that it is a date:
In clinical medicine, the question the patient asks rarely represents
their main concern. Most of what I've done in my career, and most of
what I've taught, is about how to have the back-and-forth dynamic dialoq

If the units of analysis are real spatial regions (e.g. states), how

The advantage of a cartogram is that it is a single graphic,

I've just learned about pluck() and chuck() in the purrr package. Very
cool! As I understand it, they both will return one element of a list,
either by name or by [[]] index, or even "first" or "last"
I was hoping to find a way to return all *but* one specified element of

I enjoy doing this sort of thing. Over the years I've done two full-day
"introduction to R" workshops for high school students. The workshops also
inevitably get into software-agnostic, basic issues about how to think
about data, and how to measure, record, and store it---which is all
Is the grouping beforehand necessary? Could you simply, "for all the dates
that are "4.01.2020" and have the "Value" greater than zero add 5 to the
"Value" "? I may be missing something.
