Set values in namespaces

Hello,

I want to use global variables in a package which is using a namespace.
But I don`t know how to change the values of the global variables.

I know how to get the value of the variables, e.g.

base::pi

[1] 3.141593

but following code doesn`t work

base::pi <- 3.14

Error: Object "base" not found

Thanks for your help,
Thomas Stabla
