Select single column in a dataframe by position
Introduction
We have covered basics of subsetting tibble here. If we only want to select single column of tibble for further processing using position we use the [[]] operator.
Procedure
We will be working with the following tibble:
# package for creating tibble
library(tibble)
# create tibble
basic_tibble <- tibble(
Name = c("Anthony Stark", "Steve Rogers","Bruce Banner","Carol Denvers"),
Age = c(45,115,47,80),
`Alias Name` = c("Ironman","Captain America","Hulk","Captain Marvel")
)
The tibble contains the following data:
We will select the 2nd column.
Code
# refer procedure for definition of basic_tibble
View(basic_tibble[[2]])
The output of above code is:
Conclusion
Thus we have successfully covered selecting single column in a dataframe by position.
