in r combine a list of lists into one list

Question

I cannot find out can to get a list of all entry of the sublists? Here\'s a simple example, a list o lists:

listoflists <- list(\"A\"=list(c(1,2,3),c(2,34         


        

Answer 1

We can use the concatenate function (c) within do.call to flatten the nested list

res <- do.call(c, listoflists)
all.equal(listofvectors, res, check.attributes = FALSE)
#[1] TRUE

Or as @d.b mentioned in the comments, unlist with recursive = FALSE can also work

unlist(listoflists, recursive = FALSE)
