Hi R-list,
I would like to know how to perform any elimination of attribute (column) in
R.
E.g I have:-
20,21,22,23,24,25,normal
1,2,3,4,5,5,normal
0,1,0,2,3,4,abnormal
...
I intend to do a checking on each column:-
If the column sum of abnormal is 0 but the column sum of normal is nonzero,
i
2 matches
