R Question

I would like to subset a data.frame with a combination of or/and. This is my code using normal R function.

`df <- expand.grid(list(A = seq(1, 5), B = seq(1, 5), C = seq(1, 5)))`

df$value <- seq(1, nrow(df))

df[(df$A == 1 & df$B == 3) |

(df$A == 3 & df$B == 2),]

How could I convert them using filter function in dplyr package? Thanks for any suggestions.

Answer Source

`dplyr`

solution:load library:

`library(dplyr)`

filter with condition as above:

`df %>% filter(A == 1 & B == 3 | A == 3 & B ==2)`
