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

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 c

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.

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

Hi
I think I have asked these questions earlier, but I been able to find

places). Will someone be kind enough to give me answers and enlighten me?
