plot {kernlab} | R Documentation

## plot method for support vector object

### Description

Plot a binary classification support vector machine object. The `plot` function returns a contour plot of the decision values.

### Usage

    ## S4 method for signature 'ksvm'
    plot(object, data=NULL, grid = 50, slice = list())

### Arguments

`object` | a `ksvm` classification object created by the `ksvm` function
`data` | a data frame or matrix containing data to be plotted
`grid` | granularity for the contour plot.
`slice` | a list of named numeric values for the dimensions held constant (only needed if more than two variables are used). Dimensions not specified are fixed at 0.
