Hi Tal,
In your example, note that x[[1]] is not a list; hence it must first be
coerced to a list, and attributes are lost in this conversion. This is
fairly standard in R code; eg x <- 1; attr(x, "animal") <- "cat"; x;
as.list(x), so you can't blame Rcpp for being consistent with R here.

Dear Wush and others,
Just to followup and say I've used this idea here:
https://github.com/talgalili/dendextendRcpp/blob/master/src/cut_lower.cpp
In general, it would have been better for me, where it possible to do some
(or all) of the things below:
1) Get the length of a List
2) Change the attr
Hey Dirk,
I know that linking to a shared library is not enough, and that I need
to runtime load the actual libraries that have their shared code stored
separately. I wanted to do this in a way that when loaded by someone who
installs the package, the shared libraries that I am including are

Hi Tal,

cppFunction('
std::vector temp2_fail(RObject x){

lower.push_back(x);
return(lower) ;
}
')
```
Is this what you want?

Dear list members,
I would like to be able to get an element pushed with its attributes, and I
came across the following problem:
cppFunction('
std::vector temp(List x){
std::vector lower;
lower.push_back(x);
return(lower) ;
}
')
x = list(structure(1L, animal = "cat"))
temp(
