* Pearson Example
  Create scatterplots of the Pearson's historical dataset. 
  The dataset contains 1079 bivariate observations:
  x = heights of fathers, y = heights of sons;

options ls=64 nodate pageno=1;
data heights;
   infile 'c:/datasets/pearson.txt' firstobs=2;
   input father son;
   label father='Height of Father (in)'
         son='Height of Son (in)';

* Compute correlations between 
  father's heights and son's heights;
proc corr;

* Create low resolution typewriter
  plot of heights;
proc plot;
   plot son*father;

* Create traditional SAS/GRAPH plot
  of heights;
proc gplot;
   plot son*father;

* Create more modern SGPLOT, which
  is compatible with ods graphics;
proc sgplot;
  scatter x=father y=son;
