  Perhaps the original poster is confused about the difference
between general (a la PROC GLM) and generalized (glm) linear

  The code is also a little puzzling because the same tests
seem to be run whether p>0.05 or not.  Perhaps the code
will eventually be written to log-transform the data
if it fails the normality test?

 [ hint: ?boxcox in the MASS package might be a better way
to go ]
