All true Jeff, but why do things the easy way! LOL!
My point was that various data structures, besides the list we started with,
store the names as an attribute. Yes, names(listname) works fine to extract
whatever parts they want. My original idea of using a data.frame was because
it creates
What a remarkable set of detours, Avi, all deriving apparently from a few gaps
in your understanding of R.
As Rolf said, "names(test)" is the answer.
a) Lists are vectors. They are not atomic vectors, but they are vectors, so
as.vector(test) is a no-op.
test <- list( a = 1, b = 2, c=3 )
Evan,
List names are less easy than data.frame column names so try this:
> test <- list(a=3,b=5,c=11)
> colnames(test)
NULL
> colnames(as.data.frame(test))
[1] "a" "b" "c"
But note an entry with no name has one made up for it.

Hi All,
I normally work in Emacs (28.2 build 2)) on Windows 11 pro as an admin user.
Quite a few of my analyses these days use Stan (via cmdstanr and the brms
package as example).
I upgraded R to 4.3.0 and Stan. Now, I am quite reliably getting crashes
where my R process terminates when using
Thank you to both Duncan and Ivan for the detailed answers. I'll point
the mixR maintainer at this thread in the list archive, because your
suggestions were so clear, and I can't explain them as thoroughly.
I'll keep using x as the argument name for now.
Much appreciated,
Sarah

Suppose I have the following list:
test <- list(a=3,b=5,c=11)
I'm trying to figure out how to extract the characters to the left of
the equal sign (i.e., I want to extract a list of the variable names, a,
b and c.
I've tried the permutations I know of involving sub - things like
Maybe... if you want it to act like a matrix... then you should... use a
matrix...
I think making this behaviour work with 2d arrays could be a feature, but
making it work with higher dimension arrays would be difficult, and
differentiating between 2d and higher dimension arrays could have
I really don't know. I would call it a request for extended capabilities of
[.data.frame, rather than a feature or bug. But maybe wiser heads than mine
who monitor this list can sort it out.

Interesting. There must be some caching involved. If print(a) is
resolved to print.mixfitEM at least once, it keeps failing. In a fresh
R session, where a trace()-patch is done

So is this an expected behavior or is it a bug which should be reported
somewhere else?
Thanks!
