Как мне сопоставить переменные разных размеров? [Дубликат]

Вы ищете merge()

color1 <- c("red", "blue", "yellow", "orange", "green", "brown")
assignment <- c(1,2,3,4,9,13)
color_df <- as.data.frame(color1)
color_df$assignment <- assignment

sport1 <- c("basketball", "hockey", "baseball", "soccer", "tennis", "football", "volleyball")
assignment <- c(4,3,6,1,5,7,2)
sport_df <- as.data.frame(sport1)
sport_df$assignment <- assignment

merge(color_df, sport_df, by = "assignment")
#>   assignment color1     sport1
#> 1          1    red     soccer
#> 2          2   blue volleyball
#> 3          3 yellow     hockey
#> 4          4 orange basketball
