SUMMARY: Sorting a dataframe by multiple variables

["Thompson, Trevor" <tkt2@cdc.gov>]

Thanks to Bert Gunter, Dorfman_A, Anne York, and Jingshan Zhang for their
quick responses to my question.  The simplest solution was to apply a
negative sign to the descending columns, use sort.col or order() to do an
ascending sort, and then undo the negatives.  

Thanks!!

Subject: [S] Sorting a dataframe by multiple variables


I am trying to sort a dataframe by multiple columns using both ascending and
descending order.  It appears to me that sort.col only allows one order type
to be used.  I found this question in the archives, but there were no follow
up posts.  Any suggestions on how I might accomplish this?

Thanks!
