有不同样本的多个变量x1，x2，x3
faces(x[c("x1","x2","x3")])
或者直接用help()可以查到下面这个
faces(xy, which.row, fill = FALSE, face.type = 1, nrow.plot, ncol.plot,
    scale = TRUE, byrow = FALSE, main, labels, print.info = TRUE,
    na.rm = FALSE, ncolors = 20, col.nose = rainbow(ncolors),
    col.eyes = rainbow(ncolors, start = 0.6, end = 0.85),
    col.hair = terrain.colors(ncolors), col.face = heat.colors(ncolors),
    col.lips = rainbow(ncolors, start = 0, end = 0.2),
    col.ears = rainbow(ncolors, start = 0, end = 0.2), plot.faces = TRUE)
语句的解释

xy xy data matrix, rows represent individuals and columns variables

which.row defines a permutation of the rows of the input matrix

fill if(fill==TRUE), only the first nc attributes of the faces are transformed, nc is the number of columns of xy

face.type an integer between 0 and 2 with the meanings: 0 = line drawing faces, 1 = the elements of the faces are painted, 2 = Santa Claus faces are drawn

nrow.plot number of columns of faces on graphics device

ncol.plot number of rows of faces

scale if(scale==TRUE), variables will be normalized

byrow if(byrow==TRUE), xy will be transposed

main title

labels character strings to use as names for the faces

print.info if TRUE information about usage of variables for face elements are printed

na.rm if TRUE 'NA' values are removed otherwise exchanged by mean of data

plot.faces if FALSE no face is plotted

x an object of class faces computed by faces

x.pos x coordinates of positions of faces

y.pos y coordinates of positions of faces

width width of the faces

height height of the faces

ncolors number of colors in the palettes for painting the elements of the faces

col.nose palette of colors for painting the nose

col.eyes palette of colors for painting the eyes

col.hair palette of colors for painting the hair

col.face palette of colors for painting the face

col.lips palette of colors for painting the lips
