Hi RStudio Community!

**I thank you very, very much in advance for all of your replies!**

I have a tibble (`input_tbl`

) with names (character column) and a list column (`my_list `

). For each name, I have a some numeric values (`numbers_x`

) and some character values (`name_x`

) inside the list column. The thing is that those are in a named, column-list of different dimensions. See the reprex below for a better understanding, but I'll try to explain the example below:

name `a`

has 3 integer values and 3 character values. name `b`

has 7 integer values and 7 character values. All of these lie within a list-column:`input_tbl$values`

. My goal is to take all of the integers and take them to a new column with 3+7 = 10 integers, and all the characters and take them to a column with 10 characters.

As you can see, I've tried some functions such as:` tidyr::hoist()`

, `tidyr::unnest_wider()`

but I haven't had success.
