Declaring a Const Variable in R

Question

I\'m working in R, and I\'d like to define some variables that I (or one of my collaborators) cannot change. In C++ I\'d do this:

const std::string path( \"/         


        

Answer 1

See lockBinding:

a <- 1
lockBinding("a", globalenv())
a <- 2
Error: cannot change value of locked binding for 'a'
