[R] a question on lda{MASS}

[Weiwei Shi]

hi,

assume
val is the test data while m is lda model value by using CV=F

x = predict(m, val)

val2 = val[, 1:(ncol(val)-1)] # the last column is class label

# col is sample, row is variable

then I am wondering if

x$x == (apply(val2*m$scaling), 2, sum)

i.e., the scaling (is it coeff vector?) times val data and sum is the
discrimant result $x?

Thanks.
