+4. Relevant Information:
+     This is one of three domains provided by the Oncology Institute
+     that has repeatedly appeared in the machine learning literature.
+     (See also lymphography and primary-tumor.)
+
+     This data set includes 201 instances of one class and 85 instances of
+     another class.  The instances are described by 9 attributes, some of
+     which are linear and some are nominal.
