Plot the feature importance per state. Feature importance is normalized.
Specify colmin
to obtain a plot containing all coordinates with
a feature importance larger than this minimum importance.
Specify nfeatures
to obtain a plot containing the n most important
coordinates.

pre |
prefix for saved plots |
model |
directory to xgb.model file. If NA (default) model from ./model/xgb.model is taken. |
names |
custom feature (coordinate) names file |
states |
custom states file (default=NA : states are numbered consecutively starting from 1) |
colmin |
Sets minimum of imnportance a feature has to contribute to at least one class. Can be set as vector to produce multiple plots: colmin = c(0.1,0.2,0.3) |
nfeatures |
Returns plot with 'nfeatures' most important features. Can be set as vector to produce multiple plots: c(4,5,6) |
pdim |
plot dimension (height = pdim) |
width |
plot width (pdim*width) |
