Exactly, that is what i use. I intend to do the operation using an FFI
library(i't s just a proof of concept, and there well might be
performance hits)
If such a function doesn't exist in libR.so, then i can write one.

Saptarshi,
When I need to repeatedly access data from a an R vector in C I typically
just create a pointer to the data and just use that.
double *xdat = REAL(x);
xdat[i]; //repeat as necessary
This is also displayed in 5.9.4 of the R extensions manual.
Is there a reason this wouldn't work for y
Hello,
I have a double vector, x. I can access the i'th element as
REAL(x)[i]
Is there a function for this? I know i can write my own, but was
seeing if one already exists. I did check Rinternals.h but didn't see
one.
Cheers
