I want to add that the priority for this is rather low, since we have a couple of work
arounds for the user/data set in question. I have some ideas about changing the way in
which ridge() works, which might make the problem moot. The important short-term result
was finding that it wasn't an er

Sorry. It was 3.4.2. But it doesn't matter, because my diagnosis was wrong even
there. I think (based on my reading of my outdated version) the problem is a
bit upstream in terms() as I noted in a follow

Hi Scott,
This question is appropriate for the r-help mailing list, but probably
off-topic here on r-devel.
Best,

I have very little knowledge about file encodings and would like to
learn more.
I've read the following pages to learn more:

Unfortunately, I spoke too soon.
model.frame calls formula <- terms(formula, data = data) if formula does not
inherit from class "terms" as in your case.
And that is where the bad terms.labels attribute comes from.
So, the fix I suggested won't work.
But maybe you can just supply a terms objec
You run into the same problem when using 'non-syntactical' names:

data=data.frame(check.names=FALSE, y=1:10, `Temp(C)`=21:30,
`Pres(mb)`=991:1000))

Great catch. I'm very reluctant to use my own model.frame, since that locks me into
tracking all the base R changes, potentially breaking survival in a bad way if I miss one.
But, this shows me clearly what the issue is and will allow me to think about
it.
Another solution for the user is to

Others can speak to the origins of this more directly, but from what I
recall this has been true at least since I was working in this space on the
debugcall stuff a couple years ago. I imagine the reasoning is what you
would expect: a single bit of course can't tell R both that a function
TLDR: Use gzfile(), not file() .. and you have no problems.

and fails in considerably older R versions, too.
Basically untar() seems to fail on a connection, but works fine

A user sent me an example where coxph fails, and the root of the failure is a case where
names(mf) is not equal to the term.labels attribute of the formula -- the latter has an
extraneous newline. Here is an example that does not use the survival library.

This is a not too old R-devel on Linux, it already fails in R 3.4.4, and on
macOS as well.
The tar file seems valid, external tar can untar it, so maybe an untar()
bug.
