Correct me if I'm wrong, but this seems to be the purpose of the function
`with`?

If that's the feature you're looking for, it would be the case of informing
your users to use that function when they want to refer to the colu
I think it would be helpful to describe more deeply what you're trying to

Thanks, everyone,
Following Mark suggestion:
The problem I'm trying to solve is:
Users of my package metan (https://CRAN.R-project.org/package=metan),
sometimes need to extract 2-3 variables from a given data.frame and put
them as vectors in the global environment to use in other package's
functi
I think this solution will *not* be acceptable to CRAN. (The policy

var_name <- ifelse(exists(var_name),
paste(var_name, "_vct", sep =

Hi everyone,
This can be a very simple question, but I really have the following doubt.
CRAN Policies says that 'Packages should not modify the global environment
(user’s workspace)'. So, may I or may I not create a function that will
call internally the following code? (a simple example)
assign(
