I agree with Gabor, you're not actually looking for a global state,
but a mutable object (explic
Others have already answered your direct question but consider that
what you may want without realizing it is object-oriented programming.
Here p is a proto object with components x and f. x is a variable and f is a
method. The method f sets x to a. (Presumably in reality f would do other

Global variables are strongly discouraged in R, but there are sometimes
when they may be needed and so are possible.
One example where they are used is in random number generation, every
time a random number function is called (rnorm for example) the "global"
variable .Random.seed is updated so th
