Flattens All List Levels Using Separated Names
unlist_with_sep(x, sep = "/", use.names = TRUE, depth = Inf)
| x | a list object, usually containing other lists -- of lists. |
|---|---|
| sep | character string used to separate each component of the final element names. |
| use.names | logical that indicates if the original names of each the sucessive nested list elements should be used to build the final names of the result list. |
| depth | maximum number of levels to unlist.
Root level is |
