library(tidyverse)
# assume you have this dataframe, with few values of y that are 1 or 0 and you want to filter those rows.
df <- tribble(
~x, ~y,
"A",1,
"B",2,
"C",0,
"D",-1,
"E",NA
)
df
#> # A tibble: 5 × 2
#> x y
#> <chr> <dbl>
#> 1 A 1
#> 2 B 2
#> 3 C 0
#> 4 D -1
#> 5 E NA
# filtering y to be in a set of values
df %>% filter(y %in% c(0,1))
#> # A tibble: 2 × 2
#> x y
#> <chr> <dbl>
