I understand correctly you want to name... the row names there is no way to do this unless you get the row names and make a column of it You seem to think row names is a column

I am not sure, my answer will be useful or not. But I faced same problem and I solved this problem in following way.

library(tidyverse)

rownames_to_column(mtcars,var = "Type") -> df
df

Thanks!!...

It will work if first column contains this names. But if this first column is attribute `rownames` then I'm afraid there is nothing we can do about it. – bartektartanus Apr 12 '14 at 16:12

not working... this just rename the second column... and if i try to do col.names(cars)[0] its give me error: Error in col.names(cars)[0] – user1984762 Apr 12 '14 at 16:14
Actually I think that the functioni is: colnames(df)[1] – user2097810 Apr 12 '14 at 16:15
