No guarantees on this code... If you have better ways of doing these or other plots in SAS, we would very much appreciate seeing your code.

SOURCE CODE	WHAT IT DOES	GRAPH FILE
6c.fev.dot.sas	dotplot of FEV1 by year	6cfevdot.ps
6c.gender.avg.sas	average FEV1 over years by gender	6cgenderavg.ps
6c.overall.sas	FEV1 line plot over years	6coverall.ps
6c.smooth.sas	smoothed FEV1 over years by gender	6csmooth.ps
alz.plot.sas	alzheimer's line plot over time by gender	alz.ps

Note to UNIX users: for some reason the .ps files cannot be viewed properly in Ghostview (part of the plot gets cut off), but they can be printed properly.
