Looking at shash in unique.c, from R-2.10.1 I'm wondering if it makes sense
to hash the pointer itself rather than the string it points to?
In other words could the SEXP pointer be cast to unsigned int and the usual
scatter be called on that as if it were integer?
shash would look like a

clang is compiler http://clang.llvm.org, it is fast and better c compiler then
gcc, yesterday i use clang and gfortran compile R.
The only two change in source code is :
1. the configure file (in confiure when test include wctype.h,gcc can compile
but clang need include both wchar.h
Hi all,
I'm hoping someone could tell me what best practices are as far as
keeping programs organized in R. In most languages, I like to keep
things organized by writing small functions. So, suppose I want to
write a function that would require helper functions or would just be
too big to write

As you mention ease of debugging basically precludes subfunctions so
style 1 is left.
Functions can be nested in environments rather than in other functions
and this will allow debugging to still occur.
The proto package which makes it particularly convenient to nest
functions in environments
Ben--
FWIW my general take on this is:
- Namespaces solve the collision issue.
- Style 2 tends to make for unreadably long code inside Foo, unless the
subfunctions are really short.
- Style 3 is too hard to work with
- So I usually use a variant on style 1:
### Style 4
configure is a generated file, and so should not be edited directly.
You have not told us what version of R these patches were against, but
it looks to me as if wchar.h is included already in current R
(R-patched/R-devel) -- certainly in the second case before wctype.h.
