[R-pkg-devel] Subject: cerr, cout, rand, and srand

This is well documented in Writing R extensions:

 - https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Printing for I/O streams

 - https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Registering-native-routines for native routine registrations.


As for the random number generator, you should use the one provided by R: https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Random-numbers

Hi Everyone,


My Package did not pass the pre-test with following Note.

I am not sure how to fix this problem.

Any advice will be really appreciated.

Many thanks,


In Ho

Compiled code should not call entry points which might terminate R nor
write to stdout/stderr instead of to the console, nor the system RNG.
It is good practice to register native routines and to disable symbol
search.
