Are you limiting this to the specific situation Dennis described, or
making a more general claim? The more general claim is clearly false.
Lots of packages return useful results usi

The return value from .C will almost never be useful. If you want to bring
results from the C environment into R, you need to do it by passing an address
to
.C which will receive the result.
You may find this document helpful when interfacing R to C:

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

You really need to read the "Writing R Extensions" document. It warns you
against performing I/O from C code linked to R.
You probably ought to read the Posting Guide, also, since this question is off
topic here

Colleagues,
I am experimenting with incorporating C code into R. After compiling the C
code with:
R CMD SHLIB -o FILE.so FILE.c
and executing:
dyn.load(“FILE.so”)
(without any errors), I execute the following R functions in a terminal window:
