Macro: grbiplot
Description: Generates a graphical object containing the coordinates for the biplot of a given matrix.

Link:
Usage: y = grbiplot(x,r,k)
Input:
x n x p matrix (n >= p) (n cases, p variables)
r number, rank of approximation (d <= p)
k number, 0 <= k <= 1
Output:
b n+p x d matrix, containing the coordinates for the biplot

Note:

Example:
; loads the library graphic
library("graphic")
; reset the random generator
randomize(0)
; generate a normal distributed dataset with
; 5 rows and 3 columns
x = normal(5,3)
; produce a biplot in 2-space
b = grbiplot(x, 2, 0.5)
; create a display with one window
d = createdisplay(1,1)
; show the biplot in a display
show(d,1,1,b)
Result:

shows a biplot
