[Rcpp-devel] deprecated functionality in Armadillo 2.3.x / 2.4.x and onwards

[Dirk Eddelbuettel]

Hi Conrad,

Thanks so much for proactively posting here!  [ And a fresh question below,
please read on. ]

It has been in SVN for two days, and builds since yesterday thanks to
Romain.  However, a single unit test fails:

    ComplexVector xx(x) ;
    arma::cx_mat m = forward( exp( xx ) ) ;

    return wrap( m ) ;

Passing a simple ComplexVector of ours on create a 'boom'.  Hopefully not a
biggy to fix.

| Support for tying writeable auxiliary (external) memory to _fixed
| size_ matrices is deprecated. Instead, you can use standard matrices
| with writeable auxiliary memory, or initialise fixed size matrices by
| copying the memory.  Using auxiliary memory with standard matrices is
| unaffected.
| 
| The .n_elem_slice member variable of the Cube class is deprecated. You
| can get equivalent information by multiplying .n_rows with .n_cols.
| 
| Member functions .print_trans() and .raw_print_trans() are deprecated.
| Instead, you can chain .t() and .print() to achieve a similar result:
| .t().print()
| 
| The .t() and .st() member functions have been added in version 2.3.91.
| They are shorter and more flexibile forms of transposes:

Cool, thanks.  While I have your attention:  the R and the CRAN
infrastructure now also test for use of std::cout in linked-in libraries (as
R has its own i/o buffering; one shall not mix with iostreams):

  Found ‘_ZSt4cout’, possibly from ‘std::cout’ (C++)

Compiled code should not call functions which might terminate R nor write to stdout/stderr instead of to the console.  The detected
symbols are linked into the code but might come from libraries and not actually be called.

See ‘Writing portable packages’ in the ‘Writing R Extensions’ manual.

A quick grep shows that there isn't that much code using it.  Would you be up
for defining a new #define (which defaults to TRUE for you but FALSE for
RcppArmadillo) so that we could build without?  I'd be happy to prepare a
patch for you.  If not, we'll just live with the warning as I'd rather not
constantly patch you code for each new release.

Cheers,  Dirk
