Dear all,
I have a function "fn" with its own environment, i.e.
env <- environment(fn)
and env is not .GlobalEnv. And another function
getValue <- function(x) environment(x)$mylist
which returns the list object "mylist" which is in "env". If I want to
modify "mylist", I could write
'getValue<-' <- function(x, value) { environment(x)$mylist <- value}
which gives not the desired result, e.g.
getValue(fn)[[1]] <- 3
will set the first list entry of "mylist" to 3. But then "fn" will also
be 3!
environment(fn)$mylist[[1]] <- 3
does set the list entry correctly while keeping "fn". What's the
difference?
Cheers,
Daniel
