Yes, thanks for following up on thread here. And thanks again for clearing
things up, your email was a finger snap of clarity on the whole issue.
I'll add that actually it was data.table's code at fault on the storage
conversion -- note that if you use an arbitrary sub-class 'foo' with no

With thanks to Krzysztof Banas (and Joshua Ulrich),
Almost 2.5 years ago, there's been a bug report that never made
it to https://bugs.r-project.org/ and has been forgotten
... until I've stumbled over this again.
I've found an easy fix (and improved readability also by adding
comments) and com
Yes, it is important that it only happens with certan BLAS, so probably not
really an R issue.
However, there has been some concern over the C/Fortran interfaces lately, so
if you could narrow it down to a specific BLAS routine, it could prove useful
for the developers.
One fairly easy thing t

Hello Alexandre,
there are two sides of your question it seems to me:
- there is no possibility to extend the R parser with new syntax. The R
parser knows to internally "rewrite"(*) things such as
if (a>b) print(1) else print(2)
into
`if`(a>b, print(1), print(2))
The parser has a fixed set
With a bit of meta programming that manipulates expressions, I don’t think this
would be difficult to implement in a package. Well, as difficult as it is to
implement a CAS, but not harder. I wrote some code for symbolic differentiation
— I don’t remember where I put it — and that was easy. But
perhaps you don't need this anymore but now after extract the dimension m, n,
we can simply generate arma matrix as
mat an_arma_mat(REAL(RA), m, n);
similarly you can convert RB to an arma matrix pointer, operate on it then
return directly RB to R.
I am testing a simple C++ function that takes
Fixed in R-devel and R-patched.
