ERROR IN GGPLOT IN的Rx變量是離散

Question

當執行下面R代碼裏面，收到錯誤，如： -

代碼： -

ggplot(train,aes(x = Pclass,fill=factor(Survived)))+ 
geom_histogram(width = 0.5)+ 
xlab("Pclass")+ 
ylab("TotalCount")+ 
labs(fill="Survived") 

錯誤： -

Error: StatBin requires a continuous x variable the x variable is discrete. Perhaps you want stat="count"?

可能是什麼可能的原因？ 請幫忙。 感謝

Answer 1

試試這個可能：

ggplot(train,aes(x = Pclass,fill=factor(Survived)))+ 
    geom_bar(width = 0.5)+ 
    xlab("Pclass")+ 
    ylab("TotalCount")+ 
    labs(fill="Survived")
