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