Usage
"plot"(x, data, formula = NULL, fill = TRUE, grid = 50, slice = list(), symbolPalette = grDevices::palette(), svSymbol = "x", dataSymbol = "o", ...)
Arguments
x
An object of class alphasvm
data
data to visualize. Should be the same used for fitting.
formula
formula selecting the visualized two dimensions. Only needed if more than two input variables are used.
fill
switch indicating whether a contour plot for the class regions should be added.
grid
granularity for the contour plot.
slice
a list of named values for the dimensions held constant (only needed if more than two variables are used).
The defaults for unspecified dimensions are 0 (for numeric variables) and the first level (for factors).
Factor levels can either be specified as factors or character vectors of length 1.
symbolPalette
Color palette used for the class the data points and support vectors belong to.
svSymbol
Symbol used for support vectors.
dataSymbol
Symbol used for data points (other than support vectors).
...
additional graphics parameters passed to graphics::filled.contour and plot.
