How to filter rows using tidyverse in r?

Question

Thought it would be an easy task but is giving me quite a headache. I am trying to filter rows when a particular conditio n is met, however, i am getting an error. Below is a sample code

library(tidyverse)

DF = data.frame(id = sample.int(20,20, replace = TRUE), A = runif(20, 100, 150), Dat = runif(20, 400,700))
DF_1 = DF %>% filter(id == c(6,8,17))

But the code give me below warning with a DF_1 data.frame that has only data when id is equal to 8 and 17 while it should be giving me a data.frame for id being equal to 6,8, and 17.

Warning message:

In id == c(6, 8, 17) : longer object length is not a multiple of shorter object length

Answer 1

You should filter using %in% instead of == .

DF_1 = DF %>% 
  filter(id %in% c(6,8,17))
