displays the colored decision regions of a neural network model. Data symbols are also optionally displayed. Data and model should be 2D.

|
nnet.model |
a neural network model, as returned by nnet (nnet library) |
datamatrix |
a matrix of row-elements. |
datalabels |
matrix of binary indicator variables for labels (as used by nnet). |
subset |
vector of indexes of a data subset to be displayed. If NULL, all points are displayed. |
displayPoints |
if FALSE, only decision regions 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 decision regions associated to the parametrized neural network.
