Hey there!
Welcome to the forum. It always helps if you have some data we can access directly so we can provide code that will work on the problem at hand. Minimal reproducible examples are the best.
It immediately seems evident that the second never is in fact "never " with a space. A great way to select columns you want to keep is via dplyr:
library(tidyverse)
df <- iris %>% select(Sepal.Length, Species)
df
In this example, you can see I took the iris data and asked to pipe it into the select function to only return Sepal.Length and Species into my dataframe called df which has now excluded the other 3 columns.
Hope this helps?
