[R] ipred and lda

[Stefan Böhringer]

Dear all,

can anybody help me with the program below? The function predict.lda
seems to be defined but cannot be used by errortest.

The R version is 1.7.1

Thanks in advance,

	Stefan

library("MASS");
library("ipred");

data(iris3);
tr <- sample(1:50, 25);
train <- rbind(iris3[tr,,1], iris3[tr,,2], iris3[tr,,3]);
test <- rbind(iris3[-tr,,1], iris3[-tr,,2], iris3[-tr,,3]);
cl <- factor(c(rep("s",25), rep("c",25), rep("v",25)));
z <- lda(train, cl);
predict(z, test)$class;

data.frame(class=cl, train);
flowers <- data.frame(class=cl, train);
errorest(class ~ ., data=flowers, model=lda, estimator="cv",
predict=predict.lda);

Error-Message is :
Error: Object "predict.lda" not found
