我想將我的直方圖的x軸分解爲31個單位。所以我用用qplot()的代碼:)scale_x_continuous()和scale_x_discrete()在R中不起作用
qplot(x = dob_day, data = pf) +
scale_x_discrete(breaks = 1:31)
並採用ggplot(:
ggplot(data = pf, aes(x = dob_day)) +
geom_histogram(binwidth = 1) +
scale_x_discrete(breaks = 1:31)
但無論哪種代碼不更新的情節。相反,控制檯顯示
scale_x_discrete(breaks = 1:31)

同樣的,scale_x_continuous()在控制檯顯示情況:

我不相信你。 'ggplot(data = pf,aes(x = dob_day))+ geom_histogram(binwidth = 1)+ scale_x_discrete(breaks = 1:31)'不會給出這個輸出。有些東西你沒有告訴我們。請提供一個可重複的例子。 (你最後顯示的是另一個東西,在那裏你不用'+'把刻度添加到繪圖中。) – Roland
Right ...'scale _ *()'函數返回一個無用的'ggproto'對象本身(大多數情況下)。你得到的輸出是如果你自己運行'scale _ *()'函數會發生什麼。您需要將其添加到情節纔能有用。 – Gregor
@羅蘭,相信我或者不信,這就是發生的事情。我試圖在RMD和它的工作中運行相同的代碼! – Mehul007
