這是關於該主題的錯誤消息。當我嘗試運行naive.bayes分類器時遇到此錯誤。這裏是我的訓練數據的彙總:參數的'type'(字符)無效
'data.frame': 7269 obs. of 193 variables:

這是naive.bayes()
行:
model <- naiveBayes(as.factor(class) ~ ., data = as.matrix(train), laplace = 3)
誰能告訴我它爲什麼發生?:
Error in sum(x) : invalid 'type' (character) of argument
由於'as.matrix(train)',最終你的數據被轉換爲字符。試試'model < - naiveBayes(class〜。,data = train,laplace = 3)'或者最終'model < - naiveBayes(train $ class〜。,data = train [,-c(「class」)],laplace = 3)' – jogo
@jogo它的工作!謝謝!我想接受你的答案,但是如何? – Whcrs
我現在就回答了。第一個變體還是隻有第二個變體? – jogo
