this question has nice solution of flattening lists while preserving data types (which unlist not): flatten = function(x, unlist.vectors=f) { while(any(vapply(x, is.list, logical(1)))) { if (! unlist.vectors) x = lapply(x, function(x) if(is.list(x)) x else list(x)) x = unlist(x, recursive=f) } x } if give following list, behaves expected: > = list(c(1,2,3), list(52, 561), "a") > flatten(a) [[1]] [1] 1 2 3 [[2]] [1] 52 [[3]] [1] 561 [[4]] [1] "a" now i'd restructure flat list a . relist fails miserably: > relist(flatten(a), skeleton=a) [[1]] [[1]][[1]] [1] 1 2 3 [[1]][[2]] [1] 52 [[1]][[3]] [1] 561 [[2]] [[2]][[1]] [[2]][[1]][[1]] [1] "a" [[2]][[2]] [[2]][[2]][[1]] null [[3]] [[3]][[1]] null now, of course relist(unlist(b), a) loses data types again. way restructure flat list? bonus points if handles analogous attribute unlist.vectors correctly. one way is: relist...
