Any plans for ALTREP lists (VECSXP)?
Hi Kylie,
Is it a list with only numerics in it? (I only see REALSXPs there, but
obviously inspect isn't showing all of them). If so, you could load it up
into one big vector and then also keep partitioning information around.
Bioconductor does this (see ?IRanges::CompressedList ). The potential
benefit here being that the underlying large vector could then be a...

Timing of SET_VECTOR_ELT
Assume a C program invoked by .Call, that returns a list.
Near the top of the program we allocate space for all the list elements. (It is my habit
to use "xyz2" for the name of the R object and "xyz" for the pointer to its contents.)
PROTECT(means2 = allocVector(REALSXP, nvar));
means = REAL(means2);
PROTECT(u2 = allocVector(REALSXP, nvar));
u = REAL(u2);
PROTECT(loglik2 = allocVector(REALSXP, 2));
loglik = REAL(loglik2);
PROTECT(rlist = mknamed(VECSXP, outnames));
Can I assign the individual elements into rlist using SET_VECTOR_ELT...

Subsetting a vector in C
I have a pretty simple question. I have an array of REALSXP allocated as:
rsp = allocVector(REALSXP,n)
and I simply want to pass subsets of rsp of size q (q<<n), for example, to an
R function in C. Is there a way to subset rsp without creating a new REALSXP
vector and copying the values for subsetting into it and then passing it to
the function?...
