[英]How to solve for importance in R
When I typed the command for importance as below importance ( model.rf
) I get this error: 当我输入重要性命令如下重要性( model.rf
)时,我收到此错误:
Error in UseMethod("importance") : no applicable method for 'importance' applied to an object of class "c('randomForest.formula', 'randomForest')" UseMethod中的错误(“重要性”):对于“c('randomForest.formula','randomForest')”对象的“重要性”没有适用的方法“
How to solve this error? 如何解决这个错误?
output.forest <- randomForest(nativeSpeaker ~ age + shoeSize + score, data =
readingSkills,importance=TRUE)
#You can use like this - Solution
out.importance <- round(importance(output.forest), 2)
print(out.importance )
first convert importance to variable and then print that out. 首先将重要性转换为变量,然后将其打印出来。
