Slice 2nd half of data frame in R

Question

I can easily slice the 1st half (or any other percentage) of a data frame using:

library(dplyr)    

df <- data.frame(x = 1:10)

df %>% 
  slice(seq(0.5 * n()))

However, how can I slice the 2nd half of my data frame?

Answer 1

With negative indices

library(dplyr)    

df <- data.frame(x = 1:10)

df %>% 
  slice(-seq(0.5 * n()))
