Hi there, couple of questions on data frames:

  1. Is there a way to build an empty data frame, containing nothing but the data frame variable names?
  2. Is there a way to reorder the variables in a data frame, e.g. When I go to write out a data frame using write.table or write.matrix, I want the output in a certain order...
  3. How to I "append" to the bottom of a dataframe?
