値「2018」を含む列のすべての値を NULL に置き換えたいデータフレームがあります。
列のすべての値がリストであるデータセットがあります。NULL も含まれています。値の 1 つがリストではないため、NULL に置き換えたいと考えています。NA に置き換えると、その列のデータ型が混在します。
以下のような列がある場合、2018 を含む値を NA ではなく NULL に置き換えるにはどうすればよいですか?

私の最終的な目標は、この関数をこのデータセットで使用して、action_types を独自の列にすることです。この関数は、リストまたは NULL がアクション列にある場合に機能します。
fb_insights_all<-df %>%
as.tibble() %>%
filter(!map_lgl(actions, is.null)) %>%
unnest() %>%
right_join(select(df, -actions)) %>%
spread(action_type, value)
Error: Each column must either be a list of vectors or a list of data frames [actions]
