You can use - like this:
x - 1:3
local(x[1] - x[1]+1
This isn't an environment problem. Assigning something to a get call
doesn't make any sense. Use assign.
a - 5
get(a) - 10
Error: couldn't find function get-
And from the ?assign help page, you can pick what environment you want
to make the assignment. Just pick the parent environment.
Assign() re-binds the value, not modifies it (the latter is what I
needed)

Hi,
Is it possible to modify an object in the parent.env (as opposed to
re-bind)? Here is what I tried:
x = 1:3
# try to modify the first element of x from within a new environment
local(get(x, parent.env(environment()))[1] -
]
