查找每个ID的重叠日期范围

Question

我有以下小标题：

tibble::tribble(
  ~person_id, ~mandate_start, ~mandate_end,
         160,   "1939-04-03", "1971-05-23",
         160,   "1935-04-29", "1939-04-02",
         976,   "1935-04-29", "1943-05-02",
         976,   "1951-04-30", "1958-09-01",
         982,   "1939-04-03", "1943-05-02",
         982,   "1947-05-05", "1955-05-08",
         989,   "1943-05-03", "1951-04-29",
         989,   "1935-04-29", "1937-10-18",
        1333,   "1943-05-03", "1955-05-08",
        1333,   "1959-04-27", "1971-05-23"
  )

我需要确定每个person_id重叠的任务。我应该怎么做？上面的小标题只是更大的小标题的快照。

my_tibble %>%  
+   arrange(person_id, mandate_start, mandate_end) %>%  
+   group_by(person_id) %>%  
+   mutate(previous_end = lag(mandate_end), 
+          next_start = lead(mandate_start)) %>% 
+ ungroup %>%  
+ mutate(overlap_with_prev = !is.na(previous_end) & mandate_start <= previous_end, 
+        overlap_with_next = !is.na(next_start)   &  mandate_end >= next_start)
# A tibble: 10 x 7

几个月前，我问了这个问题。这就是答案：

Count rows matching a criteria relative to current row
