##### Predict Method for `l1ce' Objects

This is a method for the generic function `predict`

for class `"l1ce"`

, typically produced from
`l1ce()`

. When `newdata`

is missing, the
fitted values are extracted, otherwise returns *new* predictions.

##### Usage

```
## S3 method for class 'l1ce':
predict(object, newdata,
type = c("response"), se.fit = FALSE, ...)
```

##### Value

a vector of predictions.

##### Warning

`predict`

can produce incorrect predictions when the `newdata`

argument is used if the formula in `object`

involves
transformations, such as `poly(Age, 3)`

or `sqrt(Age - min(Age))`

.

MM: Not sure this is true for R....

##### Examples

```
data(Iowa)
l1c.I <- l1ce(Yield ~ ., Iowa, bound = 10, absolute.t=TRUE)
p10 <- predict(l1c.I, newdata = Iowa[10:19,])
stopifnot(all.equal(p10, fitted(l1c.I)[10:19]))
```
