obtaining the discriminant line from lda
...f linear discriminants:
LD1
value 0.0357248
> XY.lda$svd
[1] 55.63543
> XY.lda$class
NULL
> XY.lda$posterior
NULL
Question #1: How do I obtain the line that lda thinks divides the
two groups? (which here it is between 1 and 2.)
Next I load in a test set for prediction:
> Predict0

1 -10
2 -9
