Due to problems with memory, I would like to know if it is possible to
append a dataset only using a specific observation.
For example, suppose we have the following datasets:
DATASET 01
variable1
1
2
3
4
5
6
DATASET 02
variable1
4
45
12
56
28
The objective is to add to dataset 01 only one out of 5 observations of
dataset 02 without creating a tempfile.
----------------------------------------------------
Start with dataset02 and reduce it:
use dataset02
keep in 1 // keep the first observation if that is what you
want
append dataset01
Hope this helps
