Abstract
In SAS and SPSS, selecting variables for an analysis is simple, while selecting observations is often much more complicated. In R, these two processes can be almost identical. As a result, variable selection in R is both more flexible and quite a bit more complex. However, since you need to learn that complexity to select observations, it does not require much added effort.
