Extraction from Tibble

[priscillaagyen]

How do you extract a single column from a tibble?

[FJCC]

If the tibble is named Orig and you want the column named id:
This will give you a vector of the values

Orig$id

This will also give you a vector of the values

Orig[["id"]]

The following two commands will give you a one column tibble

Orig["id]

library(dplyr)
select(Orig, id)

R gives you lots of ways to do this!

Yet another way is using pull from the dplyr package - this gives you the column as a vector:

df %>%
  dplyr::pull(col)

or if you want to be a real special snowflake you can use %$% from magrittr:

library(magrittr)
df %$%
  col
