Macros:
- Current versions of these and others can be found at
  http://www.math.yorku.ca/SCS/sasmac/
- Copy these to a directory reserved for SAS macros, e.g., ~/sasuser/macros
  or c:\sasuser\macros
- To make these 'autoload' prepend this path to your SASAUTOS in your
  autoexec.sas file, e.g.,
    options sasautos = ('~/sasuser/macros' '!SASROOT/sasautos');
    options sasautos = ('c:\sasuser\macros' SASAUTOS);

macros/biplot.sas	Generalized biplot of observations and variables
macros/canplot.sas	Canonical discriminant structure plot
macros/caption.sas	Annotate a plot title or caption
macros/contour.sas	Plot bivariate data ellipses [renamed to ellipses]
macros/ellipses.sas	Plot bivariate data ellipses
macros/equate.sas	AXIS statements for a GPLOT with equated axes
macros/gdispla.sas	Device-independent DISPLAY/NODISPLAY control
macros/hemat.sas	HE plots for all pairs of response variables 
macros/hemreg.sas	Extract H and E matrices for multivariate regression
macros/heplot.sas	Plot Hypothesis and Error matrices for a bivariate effect
macros/panels.sas	Display a set of plots in rectangular panels
macros/scatmat.sas	All pairwise plots for n variables

Data files:
- These are used via %include statements of the form
  %include data(iris);
- Copy these to a directory reserved for SAS data files, e.g., ~/sasuser/data
- Add the following FILENAME statement to your autoexec.sas file
    filename data           '~/sasuser/data';

data/iris.sas		Anderson/Fisher iris data
data/pottery            Tubb et al data on Romano-British pottery
data/rohwer.sas 	Rohwer data on cognitive ability and PA learning
data/soils.sas		Horton et al data on soil composition
data/*.dat              space or tab delimited data files for the above

Examples:
- These all use a common goptions.sas file to set graphics options according
  to my preferences.  In my autoexec.sas file, I define
    filename goptions       '~/sasuser/goptions.sas';
  so that %include goptions' works.
