R: Plotting the LASSO path

Plotting the LASSO path {penalized} | R Documentation

## Plotting the LASSO path

### Description

Plotting a LASSO path fitted using `penalized` with `steps > 1`.

### Usage

    plotpath(object, labelsize = 0.6, standardize = FALSE, ...)

### Arguments

`object` | A `list` of `link{penfit}` objects calculated for the same data but different `lambda1` values. This object can be created using the `link{penalized}` function using the `steps` argument.
`labelsize` | Sets the size of the variable labels in the plot. Set to zero for no variable labels.
`standardize` | If `TRUE`, plots the regression coefficients for the covariates standardize to unit second central moment. See `penalized` for details on standardization. Note that the standardization in `plotpath` can also be used if standarization was not used in `penalized`.
`...` | Any other arguments will be forwarded to the plot function.

### Examples

    data(nki70)

    # Fit the model with the steps argument and plot
    pen <- penalized(Surv(time, event), penalized = nki70[,8:77],
        data = nki70, lambda1=1, steps = 20)

    plotpath(pen)
