I'm using quantreg package version 5.98 of 24 May 2024, in R 4.4.1 on
Linux Mint.
The online documentation for quantreg says, in part, under the
description of the rq.object, "The coefficients, residuals, and effects
may be extracted by the generic functions of the same name, rather than
by the $
Years ago, I recall creating lattice plots with two binary factors, call
them f1 and f2, as in
xyplot(y ~ x | f1 + f2, data = dd)
and I made it so the rows had strips on the left with the levels of one
factor, and the columns had strips on the top with the levels of the
other factor. Sort of lik
Hello. Running R 4.2.3 on Windows 10. Using survimer package version
survminer_0.4.9 published 2021-03-09.
I'm encountering an error with ggsurvplot() in the survminer package.
Email to the author/maintainer about 2 weeks ago has not yet resulted in
a reply.
I seem unable to produce a n.censor.ta
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

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 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 pret
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.
