具有多个条件的 R 过滤行

Question

As an example

df = data.frame(x=c(1,1,1,2,2),
              y=c(6,7,8,6,6))
df

And I want to remove this line only!

df %>% filter(x == 1 & y == 7)

So I want this output:

data.frame(x=c(1,1,2,2),
              y=c(6,8,6,6))

Does not work:

df %>% filter(x != 1 & y != 7)

Answer 1

Data

df <-
  data.frame(
    x = c(1,1,1,2,2),
    y = c(6,7,8,6,6)
  )

Code

library(dplyr)

df %>% filter(!(x == 1 & y == 7))

Output

  x y
1 1 6
2 1 8
3 2 6
4 2 6
