dplyr - How to print the head (first 10 rows) with only select variables in R

Question

To print out the first 10 rows of a dataframe in R, I am using head(data.frame, 10).

But this dataframe has 64 variables, and I only want to select 3 of those variables to show for my print out of the first 10 rows.

Can I use the head function to do this?

You can use dplyr::select first and then run head after that in a pipe :)

df <- data.frame(x = rnorm(100, mean = 1, sd = 0.5),
           y = rnorm(100, 30, 2),
           z = rnorm(100, 200, 20))


df %>% 
  select(x, y) %>% 
  head(., 10)
