You can do something like this (i'm on my phone, so you might have to change it):
Environment g = Environment::global_env() ; Environment::Binding RandomSeed = g[".Random.seed"] ; You get the current value of the binding like this: NumericVector someVariable = RandomSeed ; And then when you want to set the variable: you just do : RandomSeed = someVariable ; The Environment::Binding class acts a a proxy class.
