Silly question:
How does one sort a dataframe such that it only sorts on the characteristics
of the first column and preserves each row as an intact unit? I.e., I have a
vector of propensity scores in column one that I want sorted, but the
propensity score corresponds to other variables in columns 2-8 that must
remain connected to those scores.
Thanks!
