sasCommunity Tip of the Day
Did you know that you can use the COALESCE function to find the LAST non-missing value in a list of variables? It is just a matter of how the arguments to the COALESCE function are entered. Here is an example.
data test; input x1-x5; if n(of x:) ge 2 then diff = coalesce(of x5-x1) - coalesce(of x:); datalines; 10 20 30 40 50 . . 20 40 . 10 . . . . 15 . 25 . 55 . . . . . ; the data set ... x1 x2 x3 x4 x5 diff 10 20 30 40 50 40 . . 20 40 . 20 10 . . . . . 15 . 25 . 55 40 . . . . . .
Note ... the COALESCEC function can also be used in this manner.
