Top_n return both max and min value - R

is it possible for the top_n() command to return both max and min value at the same time?

Using the example from the reference page https://dplyr.tidyverse.org/reference/top_n.html

I tried the following

df <- data.frame(x = c(10, 4, 1, 6, 3, 1, 1)) 
df %>% top_n(c(1,-1)) ## returns an error

df <- data.frame(x = c(10, 4, 1, 6, 3, 1, 1)) 
df %>% top_n(1) %>%  top_n(-1) ## returns only max value

Thanks
