这在 dplyr 中可能相对容易。示例问题使用 Lahman 包数据。
哪个玩家在 teamID 下同时管理 NYA 和 NYN？
# get master player table
players <- Lahman::People
# get manager table
managers <- Lahman::Managers
# merge players to managers
manager_tbl <-
managers %>%
left_join(players)
我想要获取 playerID 下的玩家的结果，这些玩家在 teamID< 下同时具有 .NYA 和 NYN 行
我该如何去做呢？我猜我需要在 playerID 处分组。 berrayo01 就是答案之一。
最佳答案
按“playerID”分组后，过滤所有同时具有“NYA”和“NYN”的组%in%“teamID”
library(dplyr)
manager_tbl %>%
group_by(playerID) %>%
filter(all(c("NYA", "NYN") %in% teamID))
# A tibble: 69 x 35
# Groups: playerID [4]
# playerID yearID teamID lgID inseason G W L rank plyrMgr birthYear birthMonth birthDay birthCountry birthState birthCity deathYear deathMonth deathDay deathCountry deathState
