我经常在 library(car) 中使用 'recode' 函数来重新编码变量中的级别。直到今天，我的代码都运行良好，但现在却出现了错误。df 等没有任何变化，不确定发生了什么。
可能有人可以启发我！

我的数据框（样本）：

test<-structure(list(Avg.Salary = c("65000", "395", "82000", "128357", 
"95785", "95785"), Education = c("Doctorate", "Professional Degree", 
"Bachelor's", "Professional Degree", "Master's", "Master's"), 
Count = c("D", "D", "D", "D", "D", "364584"), Year = c(2017, 
2017, 2017, 2017, 2017, 2017)), row.names = c("540061", "540071", 
"540081", "540091", "540102", "540112"), class = "data.frame")

我的实际数据集中的级别：-

    Associate Degree           Associates           Bachelor's 
             205                   35                42446
