That's odd. You don't provide a reproducible example, but using a built-in dataset (from the help for lda) I get the Proportion of Trace given by the print.lda method.
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) z <- lda(Sp ~ ., Iris, prior = c(1,1,1)/3, subset = train) print(z) Call: lda(Sp ~ ., data = Iris, prior = c(1, 1, 1)/3, subset = train) Prior probabilities of groups: c s v 0.3333333 0.3333333 0.3333333 Group means: Sepal.L.
