|
svm.model |
a SVM model, as returned by svm (e1071 library) |
dataframe |
data.frame object, containing row-elements, and associated labels in the last variable. |
displayPoints |
if FALSE, only decision regions are displayed. |
subset |
vector of indexes of a data subset to be displayed. If NULL, all points are displayed. |
steps |
influences the resolution of the decision regions. Low values will provoke aliasing, high values are slower to be displayed. |
alpha |
alpha blending parameter between decision regions and data symbols. |
lwd |
magnification factor for the stroke width used to plot symbols. |
a new plotting window displaying SVM decision regions.
