Questions regarding ALTREP_SET_ELT APIs
Hi all,
I'm wondering if there is any way to define a `SET_ELT` function for an
ALTREP class? I see there are ` ALTINTEGER_SET_ELT` etc. functions exported
in Rinternal.h, but there is no corresponding ALTREP APIs to define them.
The only way to set the value of an ALTREP is through a pointer, which will
require that the ALTREP data is in memory. Is it on purp...

Any plans for ALTREP lists (VECSXP)?
Hello,
I was wondering if there were any plans for ALTREP lists (VECSXP)?
It seems to me that they could be supported in a similar way to how ALTSTRING works, with Elt() and Set_elt() methods, or would there be some problems with that I?m not seeing due to lists not being atomic vectors?
I was taking an approach of converting each list element (of a file-based list data structure) to an ALTREP representation to build up an ?ALTREP list?.
This seems fine for shorter lists wit...

...ethods that a class can provide:
Unserialize or UnserializeEX
Serialized_state
Duplicate or DuplicateEx
Coerce
Inspect
Length
'altvec' methods a class should provide:
Extract_subset
not Dataptr
not Dataptr_or_null
'altlist' specific methods:
Elt
Set_elt
Best,
