Dear R experts, I have a so-called person-level data frame that I need to transform into a person-period data frame.
If the lingo is unclear, the data have one row for each subject, with repeated measures data each in a separate column. I need to transform these data so that each subject has multiple rows, one for each repeated measure value. Is there a quick-and-dirty way to do this transformation?
