How to put all values from a column into a c() function. For example:
| Column A | Column B |
|---|---|
| A | 100 |
| B | 200 |
| C | 300 |
How do I get all values of Column A into c('A', 'B', 'C'), without "hard-coding" the values?
I tried using c(df$Column.A), but I'm not sure if this works/the best way to do this.

We could use dput():
dput(df$ColumnA)
c("A", "B", "C")
