Happy New Year, all!
I want to do calculations on each element of a list l, but i want
the returned list element to be named differently after the
calculation.
Is it possible to do the renaming somehow within the lapply call?
l <- list(a=NA, b=NA)
lapply(l, function(x) {names(x) <- "new name"; return(x) })
This does not work, any ideas?
It did "work" in the sense that it created a list of the same
structure with each node now named "new name". If you want that named
list to become "l", then you need to do an assignment:
l <- lapply(l, function(x) {names(x) <- "new name"; return(x) })
> l
$a
new name
NA
$b
new name
NA
