Hi
I have confusion in evaluating this expression using C. It's similar to my
previous expression with the addition of row and column specifiers. I'm
confused how to create such objects.
Covariance - round(cov(100 * SWX.RET[1:6,c(SBI,SPI,SII)]),
I thought of creating vectors for 1:6 and
I'm trying to create this object in C
SWX.RET[1:6,c(SBI,SPI,SII)]
While i am able to access and use a simple SWX.RET object, I'm getting
confused on how to create an object with the array subscripts like above.
Here is what I tried to do. It doesn't work becase [ is obviously not an
operation
Hi Martin
Here's the code. I'm stuck at one point. I cannot figure out how to print
the dimnames. I've commented it in my code:
int main (int argc, char** argv) {
SEXP e,t1,t2,val;
int errorOccurred,nx,ny,i,j;
double *v;
char x[1024],y[1024];
Rf_initEmbeddedR(argc, argv);
Hi Simon
Thanks. All the confusion between CHAR and STRING. First I read this :

In the meantime I got your reply. Then I read the documentation and it made
sense!

Hi Simon/Martin
I have updated the code. I think I may be doing mistakes with PROTECT and
UNPROTECT but the code works fine, no errors or warnings so far. Please
suggest any improvements/changes.

Uh, oh, that doc confuses things even more and is not really correct

Hi Martin
Sorry, I made a mistake, I wasn't looking at the syntactic correctness of
your code, I just followed what you suggested.
Your method is valid when I want to extract data from a class. I was trying
to get data from a covariance matrix. I'll put up code in my next mail
showing how to

Thanks. I think I got it! Read the R extensions documentation again. I don't
even need to convert to a list. This is what I did (just a demo):
#include R.h
#include Rinternals.h
#include Rdefines.h
#include Rembedded.h
int main (int argc, char** argv) {
SEXP e,t1,t2,val;

Hi
I think I have asked these questions earlier, but I been able to find
answers from the documentation (which I found poorly written in several
places). Will someone be kind enough to give me answers and enlighten me?
(as in explain with CODE?)
I want to embed R in my application and use the
