Can I convert the data in a table with one row to a table with multiple rows? What are their coding?
Original table:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Table that I want:
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
In this case an Array is probably your best bet, with an explicit OUTPUT statement. Here's a quick example with two loops.
data want;
set have;
array vals(*) val1-val16;
array new(*) new1-new4;
do i=1 to 4;
do j=1 to 4;
new(j) = vals(j*i);
end;
output;
end;
run;

I guess that one way for this approach would be:
data want (keep = new1-new4);
set have;
array vals(*) var1-var16;
array new(*) new1-new4;
do j = 1 to floor(dim(vals)/4);
do i = 1 to 4;
new(i) = vals((j-1)*4 + i);
end;
output;
end;
run;
It is very easy for IML code.
data have;
input var1-var4 @@;
cards;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
;
proc iml;
use have;
read all var _all_ into x;
close;
want=shape(x,0,4);
create want from want;
append from want;
close;
quit;
I would probably
1. add a new observation with values like 1,2,3,4,1,2,3,4,1,2,3,4,....
2. use Proc Transpose
When your dataset is large, this can be super efficiant by avoiding loops.
