that's likely to work, but it's even worse than my non-functional
version: the destructive operation on the test's caller's environment is
performed here by the callee (test), and you can get ugly surprises if
you forget that test does that.
i'd consider this (and the 'for (name in names(result))

The answers that were previously given allow you to easily extract results
from your returned list, but if I understand well, this list is created only
because you cannot return several arguments whereas you need to keep the
values of a, b, c, etc. Am I right?
Another solution would be to directly

Try this:
sapply(names(result), function(nm)assign(nm, result[[nm]], envir = globalenv()))

Dear R Users,
another problem for me is the output of a function.
I have several output variables which I give back with the list command.
test <- function{return(list(a,b,c,d,e,f,g,...))}
After the usage of the function I want to assign the variables to the output
variables.
result <
