## vsn

### Description

vsn

### Details

The main function of the package is `vsn2`. Interesting for its applications are also `predict` and the wrapper function `justvsn`.

`vsn2` can be applied to objects of class `ExpressionSet`, `NChannelSet`, `AffyBatch` (from the `affy` package) and `RGList` (from the `limma` package), `matrix` and `vector`. It returns an object of class `vsn`, which contains the results of fitting the `vsn` model to the data.

The most common use case is that you will want to construct a new data object with the vsn-normalized data whose class is the same as that of the input data and which preserves the metadata. This can be achieved by

        fit = vsn2(x, ...)
        nx = predict(fit, newdata=x)

To simplify this, there exists also a simple wrapper `justvsn`.
