I have used aplpack package
faces() method in R for drawing a Chernoff graph of the following data. I would like to draw a face with only four variables
d in order to explain why program
A is better than program
B. However, the faces() method is also using these variables for several other face features. Could you please help me to draw a Chernoff face having four features with these four variables. For example: length: a, width: d, eyes: b, and nose: c. Just I wanted to distinguish face graphs of programs A and B only with these four face features, and rest of the face features should be the same between programs A and B face graphs.
prog a b c d A 0.8 7900 70 27 B 0.3 1920 393 43
