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 Max Writing R Extensions<https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Random-numbers> cran.r-project.org 1 Creating R packages.

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.
