Hello everyone,=I have a question as to how to remove the column headers
in a data file and then replace those with titles from another file in this case
the file labeled ann (
in which the titles are all in one column).
Maybe this will help partially.
I am not sure on how to read your new column names from a file into a vector
but if you can get them into that format this should let you accomplish your
goal.
