您想绑定两个数据框的列,因此您可以简单地使用bind_cols()
:
library(tidyverse)
iris <- as_tibble(iris)
temp <- tibble(r1 = runif(nrow(iris)), r2 = runif(nrow(iris)), r3 = runif(nrow(iris)), r4 = runif(nrow(iris)))
select(iris, -Petal.Length) %>% bind_cols(temp)
# or use:
# bind_cols(iris, temp) %>% select(-Petal.Length)
这给了你:
# A tibble: 150 × 8
