R 您好，我正在尝试将分类值转换为数值，但最终出现错误，无法找到函数“quot；%>；%&引用；

我们需要加载包

dplyr

trainData_df %>%
  select(name,loan_status) %>%
  mutate (Y = ifelse(loan_status=="Charged Off","1","0"))

---

另外，不需要

ifelse

#install.packages('dplyr') # if not installed, install it
library(dplyr)
trainData_df %>%
     select(name,loan_status) %>%
     mutate (Y = ifelse(loan_status=="Charged Off", 1, 0))

---

如果希望Y为数字，请删除“1”、“0”中的引号

trainData_df %>%
     select(name,loan_status) %>%
     mutate(Y = +(loan_status == "Charged Off"))
