我正在尝试从我的树格分类模型中生成部分依赖图。我正在使用RandomForest模型，并且正在收到一条错误消息。有人会把我指向正确的方向吗？

“部分错误（rf.model，pred.var = top_five_predictors [4]，plot = false，：此函数仅适用于类`（rfsrc，grow）''或'（rfsrc，forest）的对象

。

top_five_predictors = c("annualised_mileage", "mth_since_last_serv", "age_of_vehicle_years", "num_serv_dealer_purchased", "sched_serv_warr")

#Construct the 5 plots
library(pdp)

# Annualised Mileage
p1 <- partial(rf.model, pred.var = top_five_predictors[1], plot = FALSE, rug = TRUE, plot.engine = "ggplot2")```

原文

I am trying to generate a partial dependance plot from my tree classification model. I am using randomForest model and I am getting an error message. Would someone point me in the right direction?

"Error in partial(rf.model, pred.var = top_five_predictors[4], plot = FALSE, :
this function only works for objects of class `(rfsrc, grow)' or '(rfsrc, forest)'

Here is an extract of my code:

top_five_predictors = c("annualised_mileage", "mth_since_last_serv", "age_of_vehicle_years", "num_serv_dealer_purchased", "sched_serv_warr")

#Construct the 5 plots
library(pdp)

# Annualised Mileage
p1 <- partial(rf.model, pred.var = top_five_predictors[1], plot = FALSE, rug = TRUE, plot.engine = "ggplot2")```
