Confusion Matrices
Compute the confusion matrix between two factors, or for an fda or mda object.
## Default S3 method: confusion(object, true, ...) ## S3 method for class 'fda' confusion(object, data, ...)
object |
the predicted factor, or an fda or mda model object. |
true |
the true factor. |
data |
a data frame (list) containing the test data. |
... |
further arguments to be passed to or from methods. |
This is a generic function.
For the default method essentially table(object, true), but
with some useful attribute(s).
data(iris) irisfit <- fda(Species ~ ., data = iris) confusion(predict(irisfit, iris), iris$Species) ## Setosa Versicolor Virginica ## Setosa 50 0 0 ## Versicolor 0 48 1 ## Virginica 0 2 49 ## attr(, "error"): ## [1] 0.02
