After completing the knn to R classification, how do you get a list of predictions for each of the test cases?

Question

After running knn, the classification in (R) [ http://www.r-project.org/] is there a way to list the predictions that were made for each of the test cases?

I know how to get the confusion matrix, but I also need detailed test phase results, not just a summary.

Should I run each case back through the model, as if making predictions of the development of the model? Or do I need information about the test phase?

. , , knn. ?knn

library(class)
train <- rbind(iris3[1:25,,1], iris3[1:25,,2], iris3[1:25,,3])
test <- rbind(iris3[26:50,,1], iris3[26:50,,2], iris3[26:50,,3])
cl <- factor(c(rep("s",25), rep("c",25), rep("v",25)))
fit <- knn(train, test, cl, k = 3, prob=TRUE)

,

head(data.frame(test, pred=fit, prob=attr(fit, "prob")))

#   Sepal.L. Sepal.W. Petal.L. Petal.W. pred prob
