I think what you ask isn't ideal.Each column in a dataframe should be the same data type. While column names are stored in the first row when the df is exported to CSV, they are not stored as columns in the data frame. Instead the column names are stored as a separate attribute of the df. This is why you need to use names(df) to access them, not df[1,]. I don't have access to R right now, but I think ?attributes or ??"attributes" should point you in the correct direction.
