I have a list, and would like to break the elements of the list into seperate objects in the global environment.
For example, I would like the list:
obj <- list(a=1:5, b=2:10, c=-5:5)
to be three seperate objects a, b, and c.
I tried to achieve this with:
lapply(obj, FUN = function(x) names(x)[1] <<- x[1])
But it failed, with Error in names(x)[1] <<- x[1] : object 'x' not found.
How might I achieve my aim?
There is special function for mapping list to environment:
> obj <- list(a=1:5, b=2:10, c=-5:5)
> ls()
[1] "obj"
> list2env(obj,globalenv())
<environment: R_GlobalEnv>
> ls()
[1] "a" "b" "c" "obj"
P. S. It is my comment provided as an answer
This also would work:
lapply(seq_along(obj), function(i) assign(names(obj)[i], obj[[i]], envir = .GlobalEnv))
I don't recommend it but you could use attach
> obj <- list(a=1:5, b=2:10, c=-5:5)
> attach(obj)
> a
[1] 1 2 3 4 5
> b
[1] 2 3 4 5 6 7 8 9 10
> c
[1] -5 -4 -3 -2 -1 0 1 2 3 4 5
