plotImp {splinetree} | R Documentation |
Given a named vector of variable importance measures, this function makes a barplot of the relative importances. The importances are scaled to sum to 1. An appropriate input is one column of the output from varImpY() or varImpCoeff().
plotImp(importance_vector, ...)
importance_vector |
a named vector where the names are the variables and the vector stores the importances. |

additional arguments to plot, such as "main", "cex", etc. |
imp <- varImpCoeff(forest)[,3]
plotImp(imp, main="Standardized Variable Importance")
