There is a contradiction between what the help page says and what constrOptim
actually
does with the constraints. The issue is what happens on the boundary.
The help page says
The feasible region is defined by ‘ui %*% theta - ci >= 0’,
but the R code for constrOptim reads
if (any(ui %*%

Examples are not unit tests. Examples are a convenient way of testing
some aspects of the package, but serve a rather different purpose to
tests. The R community does not emphase testing nearly as much as
other
Hi, Hadley:
What about the encouragement to add unit tests, if only disguised
as examples?
I've found the unit tests to be a powerful tool to help improve
and maintain the quality of packages to which I contribute. To this
end, Sundar and I added a column "Autochecks" to the t
Hi Spencer,
I think it is the emphasis on documentation that makes the R
development process unique. Many other languages have equivalents to
CRAN and R-forge - few others require the attention to documentation
that R does.

Hello,
In Rcpp, we use a C++ template to finalizers for external pointers:
template
void delete_finalizer(SEXP p){
if( TYPEOF(p) == EXTPTRSXP ){
T* ptr = (T*) EXTPTR_PTR(p) ;
delete ptr ;
}
}
This works fine. Or at least it has appeared to work fine for some time.
Ho
Thanks. I added rows for C++, Haskell, and PHP from your
stackoverflow.com reference. I skipped the rest because I wasn't sure
if they really fit and because I ran out of time for this right now.
More suggestions (including encouragement to study the stackoverflow.com
reference more) will b
