The actual code for the lda example is below. If anyone can reproduce the
error,
let me know. Thanks.
library(MASS)
Iris <- data.frame(rbind(iris3[,,1], iris3[,,2], iris3[,,3]),
Sp = rep(c("s","c","v"), rep(50,3)))
train <- sample(1:150, 75)
table(Iris$Sp[train])
z <- lda(Sp ~ ., Iris, prior = c(1,1,1)/3, subset = train)
>Error in if (targetlist[i] == stringname) { : argument is of length zero
