[Rd] Defining Constant variable in a package

[Christophe Genolini]

Hi all,

In my package, I define some constant. In the previous version of R, I just define then in 
"/data/constants.R" but it seems that it is no longer possible. Instead, I am asked to "define them 
in the namespace". I am not sure to understand what it means. Shall I define them in the NAMESPACE 
file?
