Dear all,
could you please advice whether it is possible somehow to modify an
external (from the point of some function view) variable by some
function-internal operators. For example
var=1
foo<-function(var){var=var+1}
foo(var)
var
[1] 1
Use functions the way they are designed to be used in R ... to return
values:

> var
[1] 2

but the goal is to get the var equal to 2 in this specific case.
Thanks!
