How do I rename the column 0 in a dataframe?

Question

I have a dataframe with 4 columns. How do I give the first column a name?

I tried using dplyr but it doesn't work.

colnames(df)[0] <- "Test"

@Dason I tried that but it doesn't work. It will just change that 3/31/2019 column to Test — Jane, Jun 15 '19 at 12:37
Try this but you should really use `rename/mutate` since you tagged `dplyr`: `names(df) — NelsonGon, Jun 15 '19 at 12:40

That's not a column, those are the row names. Within the tidyverse there's a function to create a column out of them:

 df<-tibble::rownames_to_column(df, "test")
