Other than the RServe part, I do this all the time. It works well. Perhaps we
can put together some notes off-line and then bring it back to the list.

Hi everyone,
I use the boot package within the MBESS package to automate much of
the hard part for folks interested in performing a (simple) mediation
model. The function mediation() works well, except for a (probably)
unrealistic artificial data set.
When I apply the bootstrap I sometimes get:
I have a function in R that takes another function as argument:
f - function(g, ...) { #g is expected to be a function
}
I want to see if there is a way to implement f in C and calling it from R
using .C interface. I know that I can use function pointers for my C
implementation, but I imagine
You can evaluate R functions from C, see Writing R Extension.

Yes, I think they create a baby lapply function implemented in C (Which
obviously involves evaluating a function).
Also, just fyi, you want the .Call interface, not the .C
OK, thanks. But there are two issues with using .Call:
1- I may give up performance if I am literally running R code inside C,
right? In some ways, wouldn't it defy the purpose of calling a compiled code
if I end up back in R?
2- If I use the .Call interface, the resulting code will be tailored
You can't call R code as if it is C code. It is R, and requires
that it be evaluated. How would your C know what to do with an R
pointer...
.Call is more efficient than .C, all the time. Check this list and
experiment. That said, you can still call just C within the .Call
R function, it

I wrote the following very small (one-line) patch which returns an

than
