ALTREP: Design concept of alternative string
...located outside of R, but for the string, we return a vector of
R objects allocated by R.
2. It causes an unnecessary duplication of the data. In order to return
CHARSXPs to R, It forces me to allocate CHARSXPs and copy the entire data
to the R process. By contrast, for the other ALTREP types, say altreal, I
can just return the pointer to R if the data is in the memory.
The same problem occurs for Elt_method as well but is less serious since
only one CHARSXPs is allocated. Because my package is designed for sharing
a large R object. An allocation of the memory is undesired especially when
the data...
