I would like to count and plot the number of patients addmitted to each
hospital, sorted by volume group. Patients (variable name key, n=31818
observations) are assigned a numbered ID ranging from 20000-40000.
Hospitals (variable name hospid, n=2000) are also assigned a numbered ID
ranging from 2000-5000. Each hospid likely has many key observations
associated with it. But when I plot it the program plots it based on the
numbered ID, instead of a unique values ie. 1-2000. Any thoughts on what
commands to use and how to plot this?
