Unlike many other languages, R functions don’t return multiple objects in the strict sense. The most general way to handle this is to return a list
object. So if you have an integer foo
and a vector of strings bar
in your function, you could create a list that combines these items:
foo <- 12
bar <- c("a", "b", "e")
newList <- list("integer" = foo, "names" = bar)
Then return
this list.
After calling your function, you can then access each of these with newList$integer
or newList$names
.
Other object types might work better for various purposes, but the list
object is a good way to get started.
