Dear list,
When calling R from C, what appears like a spurious error can be
triggered during the execution of chisq.test(x, y).
This is happening when the following conditions are met:
- x and y are "anonymous" C-level R vectors (they do not have a symbol),
but they are protected from garbag
Hi Elizabeth,
I have fixed this problem. See the attached function. There is also
another bug that can create a problem when control$fnscale = -1, i.e. when
the objective function is to be maximized. I have commented this in the
code and have also fixed this problem.
There is a word of caution
Elizabeth,
If you look at the arguments in optim(), you will see that the only
additional argument that is in optim but not in constrOptim is the
`hessian'. So, it makes sense to add that explicitly in constrOptim() as
well. The other additional arguments are passed to optim via the `control'
ar
Dear all,
There appears to be a bug in how constrOptim handles ... arguments that
are suppose to be passed to optim, according to the documentation. This
means you can't get the hessian to be returned, for example (so this is
a real problem, and not just a question of mistaken documentation).

Hi
I have managed to link R.dll to my Visual Studio Win32 GUI project. However
I am unable to see any of the R messages on a console.
I'm hitting a dead end trying to use R_tryEval.
Is there a way I can obtain the error message when R_tryEval fails?
Regards

I've incorporated a more correct version of 1: think about what
happens if the next method also copies over the class, for example.
(It was more complicated than that: [.AsIs was used for other classes
in R -- did you actually test your suggestion, as 'make check' failed
for me?)
