Hi

I would like to repeat a value in varaible across all the observations.

For ex:

Have:

Obs       Product        Amount         Count

1.           Apple            10.0              8

2.           Pineapple            

3.           Strawberry

4.           Kiwi

5.           Cantaloupe     

Want:

Obs      Product        Amount            Count

1.          Apple            10.0                  8

2.          Pineapple     10.0                  8

3.          Strawberry    10.0                  8

4.          Kiwi               10.0                  8

5.          Cantaloupe   10.0                  8 

Thanks in advance.

Is it always the first observation? Is this an existing dataset or does it get created this way somehow.

You can google LOCF (Last observation carried forward)

Also, does that variable somewhere in the data reset to a new value? Do both always change together or may the Amount reset separately from the count?

If there is really only a value on the first observation, you can do it this way:

data want;

if _n_=1 then set have (keep=amount count);

set have (drop=amount count);

run;

If there might be additional observations later in the data set that contain AMOUNT and COUNT then you have to go with the LOCF suggestion.  It's not all that complicated.

Good luck.

data want(drop = amount count rename = (amount1=amount count1=count));
set have;
retain amount1 count1;
if Amount ne . then amount1=amount ;
if count ne . then count1=count;
run;
