下面是朴素bayes的一些代码（某一课程老师写的）
library(bnlearn)
setwd("D:\\R_edu\\data")
orgData<-read.csv("date_data2.csv")
summary(orgData)
rm(orgData1)
orgData1<-orgData[,c("income_rank","attractive_rank","assets_rank","Dated")]
orgData1$income_rank=as.factor(orgData$income_rank)
orgData1$attractive_rank=as.factor(orgData$attractive_rank)
orgData1$assets_rank=as.factor(orgData$assets_rank)
orgData1$Dated=as.factor(orgData$Dated)
bn = naive.bayes(orgData1, "Dated")
pred = predict(bn, orgData1,prob=T)
orgData1$pred=attr(pred,"prob")[,2]
关于对预测概率的提取，我觉得写法不对，应该是以下写法（orgData1$pred=attr(pred,"prob")[2，]），请大家帮忙指出到底该怎么写。
