Please do not report documented behaviour as a bug!
See the 'check.names' argument to read.table.
In your second example you are applying as.character to a data frame, and
you seem not to realize that. We specifically ask you NOT to use R-bugs
to ask questions. (What is happening is that you got the internal codes
of the factor columns, which is not what you intended. If you want
character columns, read them as such.)
