Data frames are NOT spreadsheets. Don't treat them like spreadsheets. All
elements in a column are parts of a vector which means they all have the same
data type.
On the other hand, if you want to generate formatted output in HTML, LaTeX, or
Word, there are many tools for generating formatted tables in the data output
phase of data analysis, and it is common to convert everything to character
format intentionally then.
