I have a data frame with roughly 500 rows and 120 variables. I would like to generate a new data frame that will include one row for each PAIR of rows in the original data frame and will include all 120 + 120 = 240 variables from the two rows. I need only one row for each pair, not two rows. Thus the new data frame will contain 500 x 499 / 2 = 124,750 rows. Is there an easy way to do this with R? Thanks in advance, Don Macnaughton
