One option is this:
eapply(globalenv(), I)[c('a', 'b')]

Hi
See if this function works for you (I didn't properly test it...):
nlist=function(...) {
a=list(...);
names(a)=as.character(match.call()[2:(length(a)+1)])
return(a);
}
Ex:
> a=1:3
> b=matrix(1:10,nc=2)
> nlist(a,b)
$a
[1] 1 2 3
$b
[,1] [,2]
[1,]16
[2,]27
[3,]
Because I was simplifying the use case to make an example.
The variables are often created during various computations in functions
and in order to return more than one value from a function I have to
create a list.
Wrapping everything in a list statement would make it harder to read and
make debug
If thats what you want, why don't you do
list(a=1, b=2)

I think, you are looking for ?llist in the package Hmisc.

No, I mean this:
a <- 1
b <- 2
list(a=a, b=b)
I just find it anoying, that I have to type the names of the variables
twice.
I would like something like this instead:
list(a, b, use.var.names=TRUE)

Did you mean this:

> structure(list(1, 2), names = n)
$a
[1] 1
$b
[1] 2

I often find myself making lists similar to this
list(var1=var1, var2=var2)
It doesn't seem list has an option, to make it use the name of the
variable as name in the list.
Is there another function that does this?
