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
but the goal is to get the var equal to 2 in this
See assign, you can use '-' assignment:
foo - function(var) var - var + 1

Is it possible to do what you mentioned somehow outside of the
function. I mean that there's some function and the only thing I can
do is to point on the variable to be modified inside the function
without any possibilities to modify the very function.

Hi,
with assign,
foo - function(var){
assign(var, var+1, envir = .GlobalEnv)
}
var =1
foo(2)
var
# [1] 3
